I would be absolutely gobsmacked if they had not. The key Bluesky people, including Dorsey & Twitter project lead-turned-CEO Graber, were deeply exposed to Twitter’s inner workings & code & tech strategies & algorithms from 2019 to 2022. Dorsey probably through the present day. Regardless, any claim that could be drafted vs Facebook could be alleged against Bluesky just as plausibly, if not more so.
