I'll add in my little bit here, as I am on the other side of the fence.
1)I think the reason lots of people start to hate bands is because of their success and widespread acceptance, and sorry to be brash, but album sales dont lie. Someone will see a band do well and draw attention to their scene, hence the comments distancing such bands from where they started. And if they aren't what they used to be, then it's evolution. And it happens
2)If you think that CoF or Dimmu care more about their Image than music, then think again. A lot of effort goes into writing, and there are a lot of arguments as well along the line, the reason most people think we care more about our image is because we have one. All in all it's a package, and it helps support us doing what we WANT to do, which is make music and play live. tshirt sales, image, promotion and marketing all come down to selling a record, making the recording costs back while supporting ourselves. However, music is first and foremost in our lives, otherwise we wouldnt all be here. And I know that if it was all about image i wouldnt be playing.
3)Personally I dont care about people liking the band or not, it's just funny how many people just simply hate it to fit in. No beef with me, nor being told we arent black metal, because to be honest, and in Dimmu's case as well, both bands have gone their own way sonically, and if it pisses purists off, then it's funny, as I thought black metal was partially about pissing everyone off, not sucking each others cocks and being liked
