The entire idea behind bluesky is to keep him out of hot water and the backlash he got from people when banning trump as well as other key figures. Instead of just his company it's now a few companies together so no finger pointing can go to one company. It's still a group of A hold cconglomerates who don't want to give up their "power" but on the front end 90% of people wont read into it and instead think wow what a great company for doing that lol.

Also guess who owns "bluesky" and why you wouldn't want to build your app on top of it... Yeah that's right the platform would be centralized still.
