You thinking that something can’t be improved on is not a good reason for it to not happen.
I remember over a decade ago when people were whining about a rumored Silent Hill 2 remake (long before Bloober Team even existed). The argument was as presented here: They shouldn’t do a remake because it can’t possibly be as good as the original.
You know what I have to say to that? A Silent Hill 2 remake would not erase the original from existence. So who cares? If the remake ends up sucking, go play the original. Simple as.
Funny enough, it’s an even more effective thing to do today in regards to Steam games. For example, it’s really sending a message about the state of Payday 3 when Payday 2 has several times higher 24 hour concurrent player peaks. It really makes it clear that people wanted more from the franchise and were simply unhappy with the newest product.
That’s almost never a thing with remakes. Counter-Strike 2 replacing Counter-Strike: Global Offensive is the one that would be most recent and is probably why you’re saying this. If not, you’re probably thinking of similar such soft relaunches after large updates (which arguably applies here, though the change is so substantial that they really shouldn’t have outright replaced CS:GO).
That’s a completely separate issue and should realistically have no bearing on whether or not remakes should be made. You should focus your anger at the true problem, which is that Games as a Service is fraud. Don’t let them entangle your feelings on this such that you accept things like a remake replacing an original game as not only normal, but also an inevitability.
