I don’t know about any of the others, but at least Rocket League and Fall Guys are great examples here.

Both games already existed and were extremely successful on Steam.

Both games got bought by Epic and we were told they were going to get continued support.

Both games were then REMOVED from Steam.

Both games then started suddenly having objectively worse monetization. Both communities grew a pretty negative opinion of the changes.

Both games are objectively less popular now, though at least some of this is just age/fads.

But both games are just objectively in a worse spot than they were before. All Epic did was make them objectively worse.
