There are open source clients like Heroic that download and install GOG games.
I’m more bothered about getting a good deal and DRM free than whether they have a Linux client.
I like Steam but I’m not using them exclusively just because they have a Linux client and Proton.
Numerous publishers have refused to put the native linux version of their games on GOG because of the lack of Galaxy for linux, citing feature parity of things like Galaxy’s cloud save feature.
