Way more people use Steam than Epic Launcher. The oldest Steam accounts are 15 years old now, people have been using it for a long time when it was largely the only game in town. People may use another company's platform because they have to to play a certain game. But a lot of times it's just that other platform trying to be Steam, but not in the same league.

Are we sure that's true? Fortnite is the most popular game in the world right now.

Steam[1] still has more peak concurrent users than Fortnite at 14 million if you add the games up, while Fortnite is over 8 million[2]. Fortnite does have a huge install base, but I imagine most of them that need a store (i.e. not consoles, so basically PCs) already have Steam, and at least one game in it.

For new users that don't have steam, there might be an inventive to use the Epic games launcher, especially if there's a discount, but having games split across two systems is really annoying (but it's not too bad for one game), so I imagine without an incentive most existing Steam users will opt out, thus preserving Steam's dominance.
