When you look at the article, it sounded more like they were invited over and they felt a connection and liked their philosophies.
It didn't really tell signs that they had their arms twisted, or being outright bought for massive stacks either (because Respawn made sure to let everyone know that news).
Ah that guy, I remember his famous TF2 dance videos a few years back. Nice to see he finally got noticed and got somewhere with it (Valve's SFM is really something).
I think I got confused. I thought you were talking about Valve negatively when you said "Valve actually had the balls to acquire somebody" as if it was an unethical company take over.
