I agree 100%. I’ve personally gotten into several arguments for criticizing the band over a release I didn’t like. Every fan has the right to dislike something and to criticize it always with respect.
As for taking fans’ opinions into account during the creative process, that’s what sets apart true artists from hitmakers. Linkin Park practically never cared about what we thought and always followed their own sound. Still, here we are, years later, still talking about them (some of us have been listening since the Hybrid Theory or Meteora days).
As for CTB, I really like the song and I think it had the potential to replace BIO as the last song in the setlist. Ending the set with BIO is something I just can’t take anymore! The only problem with CTB is that it’s not as relevant within the discography as BIO is, so it’s hard to imagine it being considered as a show closer.
