Yeah I see the argument that any content behind an internet connection is DRM, but I think that stance is a bit extreme.
There are a handful of real problems on that list, but it’s like 3/20.
It’s important to maintain this list and call them out though. If I can’t expect GoG games to be DRM free I might as well just use Steam where plenty of games are still DRM free but other features of the platform are a bit better.
This will be useful if you are trying to let multiple people share your computer remotely. If you are trying to set up personal game streaming for one client at a time, try Moonlight and Sunshine (more mature, easier to setup, works on any hardware).
