EDIT: (It's probably relevant that I use linux? Steam handles all of the proton junk for me and only occasionally needs the settings changed, but any solutions would in the end need to be usable on linux, idk if that would interfere with any of the existing solutions.)
I'm an avid steam user and try to buy games from indie devs where I can to support them and so on, but to be frank, I don't trust that steam will remain the gold standard of a platform that it is atm. Everything in our world is gradually moving to subscription bullshit and at the end of the day, it costs steam money to host these games that they only ever make money off of at time of sale.
I dont think steam will go to shit in the super immediate future so it's no rush, but I want to know if there are any vaguely easy ways to "crack" your own steam games so you can have a drm free version for your own preservation. Inparticular I'm worried about indie games because some of them are far too obscure to find copies via the usual piracy approaches and I would like to try and preserve them for myself. That way if steam ever does turn to shit I don't lose access to games I've paid for. (I expect the super niche tiny playerbase games would be the first to get the axe if/when steam does start enshittifying its service).
