The problem is, some developers/publishers simply never remove Denuvo.

Some examples I can think of, Ubi seems to never remove Denuvo, SEGA has Denuvo removed for some (probably due to the Denuvo offer at that time), but most are not removed.

I guess some are simply too notorious to really get a sales boost. I really want to buy those Ubi games on 95% off. UPlay required? Bye.

Guess who’s speedrunning to the stone age.

Make a dumb EV and you immediately get a lot of clients.

An EV doesn’t need internet access, doesn’t need mics and cameras inside, doesn’t need a touchpad or a big screen.

You can.

Open a publisher page, then in the top right corner, look for a gear icon. Click it, and there’s an option to ignore this publisher.

Unfortunately there’s a limitation. This works only for those having a dedicated publisher page. For publishers without a dedicated page, Steam will fallback to the search page, which doesn’t provide a way to ignore this publisher.
