multiplayer company ownership

FYI it's "reins", not "reigns".

I think that would be best, like bobs red mill.

Employee owned (like John Lewis and Richer Sounds) or customer owned (like the supermarket)

let's hope they won't turn it into an extraction shooter.

Have they ever said publicly their intention to become a cooperative?

Though the way Valve operates, being a cooperative does sound plausible.
