Ubisofts being anti consumer? Surprise surprise!

They're not happy because they think people seeing other people not playing a game is the cause of the problem. They're wrong - it is the result of the problem - they make bad games, so people don't want to pay rip off prices for them.

Ubusift needs steam more than steam needs Ubusift. They tried to leave the platform and dictate to their users via their own store and launchers, and then realised people didn't follow them.

Steam is no paradise - it's basically a glorified piece of convenient DRM - but it's popular and they have no reason to bend to the demands of Ubisoft. Plenty of other devs that make good games that are popular have had the concurrent gamers tally work in their favour - helping people see that a game is growing in popularity or unexpectedly popular.

I suspect best case for Ubisoft is their games are somehow excluded but that'll end up being worst case because then it'll look like no one is playing their games. And I doubt Steam will want to open the can of worms of publishers dictating which features are or are not allowed on steam.
