Valve has lawsuits in the work, although not from the FTC. The fact is Valve is just slightly above the other companies, but it's a very low bar and that doesn't negate their very real effect on the industry.
I bring up Amazon because your arguments apply to them. If I told you Bezos deserves all his wealth because he has a better platform then his competitors (all three of them) and offers an easy to use website with cheap delivery, you would probably call me a bootlicker.
All billionaires and their profit making machines are bad, no exceptions imo.
