Some games choose to not release on multiple platforms - but that's not a monopoly. And other games _do_ choose to release on multiple platforms, or choose to release independently of a platform. This means the best _game_ wins. Ditto with software.
Same goes for Apple. The term "monopoly" is not really useful in this discussion. It's more about having a small number of gatekeepers. There are currently exactly 2 gatekeepers of mobile devices in the entire world: Apple and Google.
It is possible that Epic could get into a similar position as what Apple is today, but for games. My point is that I support something like this happening, even though people may think that Epic is just another gatekeeper. Gatekeepers can't be avoided, so the solution is to have more gatekeepers, so they can't abuse their power easily.
I agree but people who are criticizing Epic for this are missing the real point. It is good if Epic can actually take a big chunk of the pie. Sure you could say they're being hypocrites, but from the point of view of users and developers, it's good to have more competition in the platform arena. Currently it's basically duopoly between Google and Apple. A new actor like Epic can change the dynamics and that is good.
