First off. I don't underestimate the amount Chapek cares. I fully realize he doesn't. But, he SHOULD care. And, Disney shareholders (I am one, by the way), SHOULD care.
And, people that are upset about this are not whiners. That's insulting and petty for you to say that just because someone has a different opinion than you.
And, yeah, knowing how few people are actually willing to voice their opinion, getting 50,000 signers on an online survey in a short period of time is meaningful. I can GUARANTEE you that if someone put a petition out expressing love for all the changes Disney has made, it would not get anything remotely close to that many signatures.
