You asked a question. More than one of us has given you basically the same answer. The fact that you do not understand it does not make it absurd.
So long as this conversation is a fight to get past your persistently judgemental incredulity, I am not terribly interested in it.
Look, as someone who has argued pretty strongly for pulling Lovecraft's name out of the game, I have to say, I am also in the boat thinking that this is going too far.
Number one, beholders, as a specific example, aren't inspired by anything Lovecraftian, despite being aberrations. You can read the entirety of Lovecraft from front to back and not see a single reference to a beholder or anything resembling beholders. So, why would the Far Realms, where beholders are supposed to come from, (a "beyond known reality - a trope that Lovecraft certainly didn't invent) be problematic? Mind Flayers are Lovecraftian in the sense of being tentacle horrors, but, again, Lovecraft hardly has a monopoly on that.
Cthulhu is mentioned (AFAIR) a single time in the PHB under GOO warlocks. Pull that reference out and everything is fine.
The key here is SMALL changes. We don't need to completely rewrite things because, well, that's not answering specific issues. "Inspired by Lovecraft" is an unprovable position. Mind Flayers are just as much Japanese Hentai anime as they are Lovecraft. Sure, they are inspired by mythos stories (Brian Lumley was the inspiring author - google) but, again, Mythos stories aren't really the issue. I want to keep those - or at least those stories that aren't grounded in racism. I would just rather that direct references to Lovecraft were removed.
