Readers 13-19 do you feel like the YA demographic has been taken over by adults?

I feel like there's so many people who say how Adult readers have ruined YA and made it inaccessible to actual teenagers and now it's filled with 15-17 year old characters acting like they're 25 and having sex on every page (I'm being dramatic) the thing is all these posts are written by adults.

So fellow kids do you feel pushed out of YA? If you read YA books from 10-20 years ago do you feel like they are better written for your age demographic?
