Slightly OT, but could someone tell me what, exactly, "acq-hire" means? I thought it referred to one company acquiring another purely in order to get access to talent.

Facebook did not acquire any Carsabi assets according to the linked TC story, it simply offered the founders jobs.

Back in the day, we called that getting "hired."

Is there a distinction here (e.g. perhaps some sort of payback to investors or something) that I'm missing?
