Why the Sunami hate?

I found Sunami off Youtube, instantly loved their tracks, saw podcasts with them and they all seem like chill, down-to-earth guys. My girl and I went to see them live with Ingrown, Creeping Death and Torena, and they smashed it. Amazing show, was only disappointed they didn’t do an encore despite the chants.

Given that, on this sub and some other forums I’ve looked at, I see a lot of unexplained hate for Sunami. Is the hate justified, like something I don’t know about, or do people just hate because they got too big?

They’re probably my favorite hardcore band, tied with Extinguish and Scalp. I try not to listen to bands full of people I don’t respect, so someone tell me what’s going on!
