Again, look at how distros handled DeCSS back when that was an issue. There were just “unofficial” 3rd party repos hosted in places that didn’t care about US crypto laws.

Who cares? The source is there. Do it anyways. DeCSS was technically illegal for ages in the US. VLC (not hosted in the US) still contained it to play DVDs.

“Not allowed” and “Can’t” are two VERY different things.

Just do it anyways, fuck what he wants.

Sure you can. Absolutely nothing actually prevents it.

Can this handle plugins? I use a modded DeDRM on my Kindle Unlimited books, and so require plugin support.

Have you tried adding it to Steam as a non-steam game and then forcing compatibility for it to proton experimental in Steam?
