Bluesky audience is certain kind, more left leaning, finding corporations evil. Adobe's experiment shows that it is unlikely any big corp could go there any time until the audience is more diverse, less cancel culture.
I don't know if I would refer to Adobe as being evil, but they're definitely one of the shittiest software companies in existence. And I'm 100% convinced that they would receive the same type of welcome if they made a xshitter account today.
