Do you play knock-offs of celebrated indie games?

I've been getting more suggested game trailers on youtube and have been surprised by the number of "knock off" games. I've seen three different versions of Dregde (a game I absolutely adore) and a number that seem to be mimicking Hollow Knight. I don't even mean just like fishing or rogue like games, I mean like full on knock-offs.

I get the niche they fill, but I'm kind of curious about the ethics of it. Like, I would love to play more dredge but it doesn't appear more is on the way. But I also don't really want to support a company that is just completely ripping off everything from mechanics to art. Like this game seemingly took the actual artwork from Dredge. As a developer I think I'd be pretty pissed.

Is this really common and I'm just learning about it now? Is it the video game equivalent of Atlantic Rim? Where do people stand on playing these kind of knock off games?
