Looking at steam’s own policies, this is true for steam keys, but there is an an going lawsuit that claims steam also makes this apply to non steam-enabled games: https://arstechnica.com/gaming/2021/07/valve-issues-scathing-reply-over-the-facts-behind-a-steam-antitrust-case/
But looking mosre closely than I did previously this is based on:
So I don’t really know, but if what valve says is true (which looks like it is), then I don’t see any monopoly abuse indeed.
They do have a monopoly, but it’s in large part for providing a better service. As a Linux user, I prefer Valve 100% over Epic that buys Rocket league and discontinues linux support. I do prefer Itch and GOG for the possibility of no-DRM games, but I’ve got to say it’s overall a worse experience (no auto updates, no social features etc…)
I made my initial comment after watching: https://www.youtube.com/watch?v=mOEG5qmMQas which suggested that Steam applied the MFN for non steam - enabled games too, but was done prior to Valve’s response.
Not even Cyberpunk or the Witcher could sell more on gog than on steam even though you knew that there the developers got 100% of the money spent.
Most gamers don’t know and/or don’t care, so they will take the least resistance path, which is Steam.
Steam has a “most favoured nation clause” which prevents companies from actually selling for cheaper on other platform. This is how steam maintains its monopoly. If it were possible for CD Projekt Red to sell it cheaper outside of steam it would force steam to actually charge developers less.
Edit: see below, it’s actually not that clear.
The proton drive app does not have a way to automatically sync a specific directory. It’s so infuriating, because they already have this implemented for the pictures.
