I mean the devs already stated the changes are due to internal reasons and removing what "the rot" touched for a completely clean slate. I don't think they mind sexy stuff, but we don't know the connotations the removed things have behind the scenes.
We could speculate about it all-day, from my pov I suspect quite a chunk of it relates to some tasteless behavior the devs don't want to be reminded of every day. None of it really matters, most of this topic is used by bandwagoners to make money and cause drama from a place of false concern. Can't really go "fuck Blizzard for allowing the devs to get harassed, but fuck the harassed devs for making a healthier environment for themselves." with a rational mind.
