I’ve been a user of GOG for a while principally because of the no-drm ability to download a copy of what you bought. When the library starts getting past a certain size though you start to wonder about those things like what if the producer has a falling out and wants to yank it from the platform, does it vanish from my library then too? Are there contracts that say ‘forever’ when they offer it? Would love to find some ‘download all’ option to take a full copy offline of the bought items at once but it’d probably overrun the monthly ISP limits even if they had one.
Seen too many things on Netflix or Spotify that I liked vanish because ‘fuck off, we can’ and although I never anticipated it being ‘bought’ in those cases it does give a lot of justification to find alternate means to reestablish that access.
