Nothing new here. For years Mac updates would turn and leave on bluetooth, and ios updates routinely turn game centre on, and less so recently imessage and facetime. I don't know if its malice or sloppiness, but it is tiresome.
I've turned game centre off at least 20 times over the years without ever once turning it on.
