Bluesky is a quite political and far-left website, born from Twitter/X being purchased after the Twitter file scandal.
It seems an awful website for any professional to use. (I think X isn't great either).
As a business however, whatever makes SE/CSIII money I'm sure they'll be inclined to invest in. A small account on all social smaller media whether it be Bluesky or Parlor etc would increase reach for them.
