The public hate definitely got worse in the later 2000's, but it was definitely still popular among middle/high schoolers to tell everyone they hated songs like Yellow and Fix You to show how "sophisticated" their tastes were. It was the same for any band that got too popular, but I remember that when Facebook opened up to people without .edu emails in 2006 I saw the Coldplay hate all over the place. One of the first online arguments I ever had was because someone said that the song The Scientist sucked, and I was really into it at the time. It's part of why I chose my username, along with my love of biology.
