Basically, Valve is too big to compete with at this point, because any competing product needs to be more perfect out the gate for people to even consider using it. Which is hard to do when you are not as entrenched and don’t have the kind of money Valve has.



Not to mention those companies have divided priorities. Valve’s main income is Steam, they have a vested interest in keeping their product dominant. Microsoft and Epic simply don’t, because their stores are only side projects that incentivise their main income sources. But that’s not to say I want to substitute Steam with some other corpo giant’s latest money grab either.
The bigger question is why more consumer-friendly stores like GOG that sell DRM-free games can’t compete with Steam. High profile games have no incentive to release DRM-free versions of their titles on GOG because the bigger store where they make more money encourages DRM.
Valve gets a lot of clout in the Linux sphere because their adoption of open-source platforms is better than their competitors, and we have the mindset of “a rising tide lifts all ships”, but this is also what we were saying about Google and Android 15 years ago and we can see how that is shaping up. Something something “you either die a hero…”
