Half of the initial mac os x kernel was ripped off freebsd, giving pretty much nothing back.
Afaik netapp is also basing their system on bsd.
Sony uses freebsd as the OS for their playstation.
And many more, giving essentially nothing back.
That is open source.

This attitude of "OMG you're being ripped off" any time a company incorporates code from a BSD/MIT/whatever licensed project baffles me.
I’d be shocked if netapp hard forked bsd and doesn’t upstream fixes.
