Business is business
You can work with somebody that hates you, if it furthers your cause. Warring enemies unite temporarily when they see benefit. And that's with ppl who lost family to one another. If working with Gibson helped further their business and their overall cause in the grand scheme of things, they'd be fools not to.
At the end of the day, they put out great content that's needed out there, and they're growing their business. In the course of that, if a rich racist cac wants to work with them under terms that are mutually beneficial, it's all good. If Trump gave them a billion dollars I wouldn't fault them for taking the money, unless they had to do some c00n shyt to earn it.
