That was the only truly contentious user impacting change they've made over the four years the site has been around. I think your last sentence is a nonsensical justification to complain. If anything many of the recent changes have been to make the site more inclusive such as suggested edits, better review processes and so on, so that users who are still on their training wheels on the way to the the 10k and 20k tools can practice "community moderation" under the guidance of more experienced users.
