> By your definition Valve is a monopolist in the gaming market due to their size and dominance

Well, no. You can install games on your computer however you want.

If Steam was the only possible way to do so, then yeah I would say Valve had a monopoly.

(It's worth noting that Apple has already gotten in trouble for this - the EU has fined them billions and forced them to allow alternative app stores. Hopefully US regulators take inspiration and force them to do the same domestically.)
