You may be right, especially about the motives behind stuff like this. However, the original information about not focusing on DEI was not stated in a performative way by the company - it was shared in an investor chat. Next a person on Twitter commented about the Body A and B stuff and the company responded to that and later went on to make the poll. What I'm seeing so far is an effort to listen to customers and that's something positive compared to the usual condescending attitude we get (you know, gamers are toxic, bigoted, etc.).
Personally, I'm waiting to see if these changes are implemented when the game releases. The return of male/female, for example. Several gaming media sites are already writing hit pieces on the company, as well. If nothing else, I applaud their willingness to go against the activists on these sites and Twitter - not too many have been willing to in the past.
