Why do people hate them?

I was wondering why people hate them. I was searching for most hates bands and then decided to search up if Imagine Dragons are hated a lot and they are.

I know that some people do it because it is cool to hate, but is that all there is to it?. Cool to hate them?, I know critics have more reason than that but what about regular non-critics?. Why do they hate them?.

I am not sure if any of you know but as a fan I have no idea why. Btw as a side note went to their concert and they are so lively and Dan seems like a nice guy!, joking and well meaning!. I adore him!.

Anyway so if you know then I will appreciate it!.
