Team leaders at the big companies now feel far more freedom to try to recruit people from big competitors, thanks in part to the poaching agreement being found to be illegal. So it did matter. You're launching a big project, you don't have the needed expertise in house, and a guy/gal you know who works for OtherBigFAANG would be a good fit. You call them. Back when the poaching agreement was in effect, HR would tell you you can't hire them. Now they won't, in fact, they can't.
