Valve’s DRM is just about the least invasive and easiest to crack DRM systems on the market. The only way to be less invasive is to not have DRM at all. Obviously that’s preferable, but Valve’s setup is one that keeps publishers on the platform: provide a basic DRM system and allow publishers to add more if they want. If you don’t like what someone like Ubisoft does on the platform you’ve got plenty of other options (and third party DRM is clearly labeled within Steam).
I don’t think people see Gabe Newell the way you describe. They just appreciate that Valve makes business decisions that have basic respect for their customer base. They are fully aware that he’s a billionaire yacht aficionado.
Capitalism and likability are not mutually exclusive, it’s just that so many capitalists have taken the route of maximizing serfdom.
