It's a question of whether they would ever get subpoenaed really, and then whether they'd comply. I'm not sure it's worth it from the copyright holders' perspective. The individual users are getting DDL links, so they're not uploading – i.e. "sharing" – anything. These days, if holders go after anyone, it's for the sharing not the downloading. As for compliance, I don't think we have any evidence one way or the other, as (afaik) they are yet to be subpoenaed (despite running for a long time).

It's also worth noting if you do want to do this totally privately: when you buy an RD subscription, you cannot use a VPN during that process (they block known IPs). So, you would want to use a public WiFi connection somewhere, and choose an anonymous payment method like paysafecard.

You would just find the directory location of the DRM locked ebook, put it in Calibre with the DeDRM addon installed and enabled, and hey presto, you have an unlocked clone. (This works on MacOS)

True by the letter but not really by practice. PC is synonymous with a computer running Windows, or Linux at a push. I don't know whether that's because of Microsoft's early market dominance or because Apple enjoys marketing itself as a totally different entity, or some combination of the two. But yeah, usage determines meaning more than what the individual words mean in a more literal sense.

in the end, you’re leeching off a service you enjoy.

I don't think that's a fair or true statement.

For one thing, the "service" here has risen to a point of ubiquity that it's a de facto public space. Everything is on YouTube – legacy media channels, individual enthusiasts, alternative media outlets, the worlds of tech, fashion, politics, sports – you name it. If you were deprived of all access to it, you would have a qualitatively poorer access of what is going on in society. So it's not equivalent to a traditional service like a trade.

For another, blocking ads is not merely refusal to pay a fee of some kind. Advertisements are cognitively intrusive, designed to affect your willpower and decision-making, used to track and control your behaviour, compromise your digital safety, and turn you into a product for companies to whom you do not give your consent for the opportunity to be exploited. Blocking that system of "payment" is not simply prudent but right, and the choice between paying a monetary fee or being so exploited is not a fair choice at all.

For me, what works perfectly is this setup:

Desktop – Adguard

Android – YouTube ReVanced

Never get adverts ever. The day I'm forced is the day I stop using it altogether.

Considering the version you were given by the author could be watermarked in some way, and they could get into shit from a publisher if you uploaded it for mass retrieval, you ought not to do this without their express permission. It's different if you had downloaded the article from a journal/database yourself, or if it was some other version (like an unformatted manuscript).

So do people in the US chiefly send messages via SMS rather than WhatsApp and others like it? That's so bizarre to me haha.

Are we allowed FOSS alternatives to common FOSS apps lol? In which case, I'm saying NeoStore > F-Droid.

Also, separately, Zotero > all commercial reference manages and increasingly over PDF readers too.

Yeah it is pretty solid. I used to use KeepassX, which while also a very cool project, was a bit more tinkering than needed. I hosted the database on a mainstream cloud provider though, and figured at that point, you might as well use the cloud storage of a company with a great security reputation instead and just bundle all together. And so BitWarden.

Think you've missed the point a bit of OP's comment. They're asking not how the end-user is protected from copyright claims, but how the debrid service itself is.

I think to the uninitiated it's a bit of a minefield. Are there guides to the best providers, and ones you can subscribe to using anonymous forms of payment?

Guessing English isn't the first language here (a few mistakes), and what he probably meant was that refund requests would be honoured, rather than that all purchases would as a rule be refunded.
