On the other hand - I really hope this isn't a segue into more DRM or something similar to what steam does - providing a client to play games instead of actually downloading and having them. GOG is one of the last few bastions that lets you buy and own games. They've got a few in their catalog now that require proprietary launchers/drm etc and I really hope it doesn't become a trend.
Humble Bundle increasing sells steam keys instead of actual games, or sells keys to 3rd parties that DRM, or sells DRM'd ebooks etc. GOG, Humble and Itch are the last big players holding the line on DRM free stuff. I worry that if any of them slip (further) into the lucrative darkside it would be disastrous for consumers.
It's been a while since I've used GOG but it's whole shtick is that they give you the installation files to the games so you can keep them forever. Have there been new games where they haven't been able to do so and offer installation solely through the GOG dekstop client?
No... but GoG does not prevent the publisher from instituting their own launcher/DRM/malware scheme. See reviews at https://www.gog.com/en/game/horizon_zero_dawn_complete_editi... and https://www.gog.com/en/game/pathfinder_wrath_of_the_righteou...
I mean, they dont really have a way of doing that short of not allowing them to be on the Platform. If anything, letting the reviews stand as a warning is probably the right thing to do. The additional thing that they should do is probably make it top-level visible that there's Publisher DRM on-top of the game.
