Not a traditional domain name registrar (they actually hold the domain for you), but there's https://njal.la/ (they explain the reasoning on their site).

the alternative is that they don't sell replacement parts at all

maybe I'm misunderstanding, but isn't the corresponding alternative in this case "you can use parts from any manufacturer you want"?

... oh damn, I didn't catch that at all. First time hearing about them. (looks like the all caps thing is canonical too)

I guess they're completely unaffiliated with LibreOffice? looks like their product is intended to feel as close to Microsoft as possible

nah. it may not be a huge deal (esp. if you're male) and "screaming" might be exaggerating it, but "keep personal politics out of code" is classic "I consider your existence political".

I'm happy to see if the guy's politics has changed in the years since this happened, and I don't know if their involvement in the project is worthy of a boycott, but those are personal choices (and the relevant comment was even helpfully linked).

~~OpenOffice is unmaintained, unfortunately (see the LibreOffice page explaining this); LibreOffice considers officially hosting a cloud service out of their scope but~~ Collabora does provide hosting (and you can self-host, of course). Their "Development Edition" is the free version that doesn't come with an SLA.

edit: I can't read

last year was my first time; looking forward to doing it every year now

If you're willing to change up the design aesthetic and have other materials lying around (e.g. dowels, rods, some kind of sheeting), you could also just print the "end caps" with slots for the main body.

This also has the advantage of being sturdier and maybe easier to print, but the design might be more involved.

speculating here, but the "auto-generated ones" are probably just the ones in the opengraph tags, which is supposed to be what the website intended as the thumbnail. It's more likely that these websites' operators don't have a clue that opengraph is being used, but since they're the "proper" way to do embeds, lemmy can't just ignore them, either.
