So, they want lots of engineers to do work for them and then only pay the one they like?
I thought Netflix OSS is great. They're opensourcing something like 30 projects, putting on super well organized meetups with expo like rooms where you can pick Netflixers brain about the software and their internal systems in general, free food&beers, free Ts, etc. It was great.
They do it go give back to the community, to get patches and ports from the community, and hiring of course, there's nothing wrong with that!
