Yep, my brother decided to join Facebook in a non-tech role (admittedly, right before the #deletefacebook movement began), and it was purely for the compensation. He even joked he had joined "the dark side". I've been off Facebook since 2011, so it was a bit disappointing. But, the compensation was the highest out of the companies he got offers from (Google, Stripe, etc.), so I don't blame him.
In this case I'm not getting that your brother wanted to be associated with them necessarily. If compensation was equal, which do you think he'd have picked?
