Re: "Has it become that bad?" No. Not even close. The people who complain about such things are typically newbies who make the mistake of trying to "fix" articles on highly contentious topics with hundreds of edits per day. Just pick a page that hasn't been edited in a while, which is most of them. The history tab tells you how often it gets edited.
