Twitter/X has shown to be no more than a self-promotion and PR platform as soon as it became popular. Just disposable snippets (pretty much the definition of a 'twit') to drive views. The same will apply to Bluesky. It does not matter whether it is centralized or not, VC money or not, as long as it serves that purpose. In fact a centralized system probably serves this purpose better as it is easier for the users and for content reach.
