The majority of users most certainly don't care (or care enough to sign a meaningless petition). But a lot of moderators, who are essentially the unpaid employees who are driving most of the content on the site, like those popular AMAs, DO care. A lot of them are pretty upset. The lack of communication and planning makes their (volunteer) jobs harder, which makes them less eager to do those jobs.
Take the AMAs for example. When Victoria was there, the mods could do what they do: verify the person's ID, make sure it happens on time, set up the schedules, etc. When they fired Victoria, the link between the admins and moderators was gone. That left the mods with no good way to do their jobs and make all that content the company is so eager to monetize. The mgmt team shot themselves in the foot, in other words, and now all the mods are getting are platitudes and vague promises without any deliverables, timetables, etc.
More people will likely start caring when the overall quality of content goes down as mods get more and more burnt out.
