Facebook had a good idea for hiring and retention: pay the highest, and that will boost college students' perceptions of how cool you are.
Facebook got a lot of mileage out of that, running long after public scandals confirmed the early hints of possible sketchiness, back when Google was an attractive alternative.
Though I don't know that's still necessary. The job markets are different now, since there's not many tech employment options that aren't either sketchy or reviled. Anti-AI-worker sentiment seems high lately, outside of HN circles -- much more widespread and negative than I recall any kind of perception of pre-AI tech workers -- yet there aren't a lot of non-AI employment options.
So, some Flock employees might want to leave, over ethics, social status, or company internal culture, but... if they end up at a AI company, they might soon still be seeing a lot of social negative feedback anyway.
("Hi, nice to meet you. ... Me? Oh, I work on, uh, software. ... Yeah, AI is really disrupting things in my field, too. It's been a bit rough, but we're hanging in there.")
We're at the tail end of that with Meta, which is "Just hang on and get your bag!"
