There's nothing non-intentional or implicit about denying the franchise to noncitizens. For the vast majority of countries, that is the way citizenship is expressly designed to work as an in-group. Citizenship is generally meant to discriminate against outsiders.
My take: Ride as is if you can stand it, but there's no wrong answer.
I powder-coated a Motobecane of similar age and I don't regret it. The original paint job with hand-painted details must have been great, but decades of sun, rain, and neglect obliterated it. Restoration would have been starting over from scratch so I sandblasted and turned it into an electric blue beast of burden.
Somebody else can restore the original paint job 50 years from now. I'm just keeping the frame safe for them until they're done being born and growing up somewhere. It'll be waiting for them when they're ready.
Nick Cage: Is that supposed to be me? It's...grotesque.
I'll give you $20,000 for it.
Malazan Book of the Fallen was like this for me. Great worldbuilding. Big ideas and loads of characters. Lots of obscure detail, all the way down to potsherds and verdigris.
When I finished, I had a powerful impulse to reread the series immediately after finishing it.
It got a lot of press when it first showed up and it was a strong default suggestion for new users for well over a decade.
I used it for several years and I initially jumped ship to Xubuntu, so it was clearly good enough for me to want to use something similar at first. The distro-specific changes (snaps, etc.) are more likely to alienate experienced users, whereas new users are less likely to object to things like snaps.
I don't use anything Ubuntu-based these days, but it has everything to do with my specific needs/preferences. Nothing directly to do with the decisions that get bad press among long-term users.
I always assumed that a lot of this boils down to semantics and trademark law.
OpenIndiana is a direct code-line descendant of Unix System V through OpenSolaris via Solaris. Thank you for that, Sun Microsystems. I understand (but haven't looked) that a lot of code these days is simply ported over from BSD or Linux. If you compare the source code to an old copy of the Lions book, you're probably not going to see any line-by-line overlap. Thank goodness - we shouldn't be literally running old operating systems from the '80s. I don't think that OpenIndiana is Unix-certified by the Open Group (Trademark).
The BSDs started out as a sort of 'Ship of Theseus' rebuild of an academic-licensed copy of Unix around the time that AT&T was getting litigious and corporate Unixes (Unices?) were starting to Balkanize.
GNU/Linux started out as a work-alike (functions the same but with totally different code) inspired by MINIX, which in turn was an education-licensed Unix work-alike designed to show basic operating system principles to students. I think that one or more linux-based operating systems have obtained UNIX certification from the Open Group, just like Apple did for MacOS (paying money and passing some tests). It doesn't seem like any of them are still paying to keep up the certification. Does it matter if they did at one point?
Going back to proprietary corporate Unixes, I believe that IBM AIX and HP-UX still exist as products. They started out as UNIX and have been developed continuously since then. They are both Certified Unix. By now, their codebases probably diverge substantially both from one another and from all of the Unix-likes. IBM also has a mainframe OS with a fascinating history that has nothing to do with UNIX. It is Certified Unix because it passes the right tests and IBM paid for certification. It is not UNIX code and doesn't descend from UNIX code.
Simple as.
At that price range, be sure to carefully check compatibility for your favorite distribution and for any hardware that you intend to use.
For what it's worth, I have an old HP Stream 7 that currently runs Debian Bookworm. I think that it cost about $100 new. I can use it as a pdf reader and to sync files, but there are plenty of tradeoffs due to the 1gb of RAM, the weak Atom processor, the small amount of built-in storage, the mediocre touchscreen, and the general poor quality of touchscreen interfaces among low-resource window managers. Neither camera works and several distributions can't support the built-in audio. Screen rotation is a crapshoot. Forget about low-power standby. Some of these issues are unique to my tablet, but some of them are problems that people tend to run into when they try to shoehorn linux into a tablet that wasn't built with linux in mind. Something like a Pinetab would be a better bet.
I saw another person suggest an aftermarket Surface. If you go this route, carefully research the exact model number to verify that the hardware supports linux and that there is a clean way of installing your preferred distribution.
Another thing worth mentioning. Installing linux can be a special kind of hell. Most distributions don't have a touchscreen-friendly installer. For my cheap tablet, this meant cobbling together a flash drive, a powered USB hub, a USB keyboard, a USB ethernet adapter, and a USB-OTG cable for the single micro-usb port on the tablet. Then, I had to race the decade-old tablet battery to the finish line during the install process. Plus something about a 32-bit EFI bootloader combined with a 64-bit processor.
Arch seems to target users who are inclined to read the wiki and manpages, so it doesn't surprise me that beginners run across some saltiness if they approach people who aren't focused on beginners. Even the installation process seems to be designed as a screening mechanism. It wasn't a big hurdle when I first tried it out, but it was a small one.
There are plenty of distributions that focus on people who are just getting started. For whatever it might be worth, this includes several distros based on Arch. I usually suggest Mint or Xubuntu over Debian for people with no prior exposure to Linux. Even though I like it personally, I try not to suggest vanilla Arch to anybody. They can try it if they want to, but there are plenty of reasons to try something else instead.
I did a Sweet 16 bracket elimination contest for regional IPAs a few years back just to force myself to identify the 'good' ones and eliminate bad ones. Even after doing that, I do a little dance any time there's something else available.
Imperial Radch comes to mind. Really, a lot of military-focused genre fiction has shades of this. Black Company, Malazan Book of the Fallen, Old Man's War, and similar tend to have main characters that aren't exactly loved outside of their in-universe group. Someone else mentioned Consider Phlebas from the Culture series, but Use of Weapons is another stand-alone from that series that might be worth reading if you're looking for a main character who is hated for a reason.
A few enemy tears are just fine in a gin martini, either directly or as an olive brine additive.
If the lessons that I've learned about lightbulb replacement are applicable, then the nationality of the developers on the bus will impact the answer to your question.
