I feel like people are moving on to fast from things and I don't want too

I've noticed, and i'm sure a lot of people have to, that no matter what it is and how good it is or how popular it gets people are moving from one thing from another sooo fast. And I'm not saying that its a bad thing to like and indulge in a lot of things at once, but it feels like it happening over everything and then it starts getting hate because it was popular :/

And ik its like "yea captain obvious it the internet" lol, but it's just frustrating when it's getting to a point where everything is either getting really good and cool, and everyone's having a good time to a bunch of people out of nowhere saying it's bad and cringey to still like and enjoy it. 

And of course, there's still a good community of people for everything who still enjoy this stuff and they're not going anywhere, but I'm just confused on where the sudden hate comes from. Like, ik the longer something goes on there's gonna be valid criticism on it but why such a quick switch up? Is it cus it got so popular that people suddenly stop liking things? Srry if this seemed like such a "yes we know this already" rant, but I just have been really frustrated about this lately TT
