You can't steal people. You can kidnap people and you can hire people. Maybe if you kill them you can steal the body? You sound like an anti-piracy advertisement. "Piracy is theft".
Just to nitpick, because we are on HN: I remember a story of a cartel in Latin America kidnapping networking experts to force them to develop their technology stack. That may count as "stealing" talents?
You can only "buy" top people if your offer is better though. I see nothing wrong in people switching jobs for a better offer. Calling it stealing makes it sound as A Bad Thing while in truth it is a good thing for the person getting hired. If businesses shared the profits equally this wouldn't happen but then we are not in capitalism anymore..
Not sure if that's what I remember, but here is a Wired article: https://www.wired.com/2012/11/zeta-radio/
Edit: of course I'm not implying that Huawei does this...
