Good guy GOG wants you to actually own your own games, forever.

Your chosen GNU/Linux distribution installs the applications.

Nothing better than Google and Microsoft sniffing your traffic.

Lutris is great, I use it myself.

However, if you have a friend fresh from Windows who already uses steam and you say, tick compatible proton 8 or latest and click play vs install new software and then add the game you’ve already lost the easy battle.

Not true, steam makes it incredibly easy. Install steam, tick compatibility option, install, click green play button.
