The comic book industry as a whole is struggling specially with Diamond Comic Distributors going bankrupt

Same I don't think it was targeted at them, but why out of all places paint it there? The comic shop hasn't done anything wrong; it would make more sense to paint that on a big corporation's building if they really want their message to come across.

The funny thing is they don't even have a CEO; it's co-owned by the same 2 guys who started it in 1982.
