I think Valve does have a reputation for having this type of model. They've famously expressed an intention to not go public or sell the company to anyone else. This is also what leads to them being a fairly small and selective company that can afford to cherry-pick employees, and that also has an allegedly more employee-friendly culture than others. Just like the recollection in the original post, they might have that "infinite abundance" mindset - their initiatives in game development, hardware and VR are probably subsidized by Steam many times over.
