I mean, Epic published it and funded its development. It's not Remedy insisting so much as sticking to the terms of the contract that gave them the budget to make the game in the first place.
I agree that it sucks, though. At least they seem to be shopping around a bit when it comes to Control 2, so let's hope they don't end up with Epic again for that one.
Don't know if you're interested anymore but there are a ton of mods out there that fix the stability issues, including a partial engine rewrite last year.
