As did Google when Google engineers started leaving for Facebook, and FB when their engineers started leaving for Uber/Lyft/AirBnB/Stripe/Coinbase/etc, and so on. It's pretty much a revolving door now, where many engineers have worked at all these companies and sometimes even come back to their home base.
CA's prohibition against non-competes and the DoJ's lawsuit against anti-poaching agreements is basically what makes Silicon Valley work.
Oh that definitely happened, but we don't have quotes from Google like this:
Prior to joining Google, I set up a meeting on or about November 11, 2004 with Microsoft’s CEO Steve Ballmer to discuss my planned departure….At some point in the conversation Mr. Ballmer said: “Just tell me it’s not Google.” I told him it was Google.
At that point, Mr. Ballmer picked up a chair and threw it across the room hitting a table in his office. Mr. Ballmer then said: “F---ing Eric Schmidt is a f---ing p--sy. I’m going to f---ing bury that guy, I have done it before, and I will do it again. I’m going to f---ing kill Google.”
