I agree with those people, actually. I don't see why it's wrong for people to choose who they associate with. That seems like a pretty basic freedom to me.

Discrimination is the ability to tell things apart. If Google has a rule against poaching from their friends and partners, that's fine with me; if they're underpaying all of their employees, what you're really saying is that someone who doesn't participate in the cartel gets their choice of the top technical talent in the valley. If you seriously believed this, you'd be raising money for a startup to exploit it, rather than complaining about it on news.yc.
