Their co-founder (not just an employee) is bankrolling a party that’s leader has called for the expelling of all immigrants. This fact is not in dispute.

You're just playing with language. I can say:
"I'm surprised the co-founder of a freedom of speech company is contributing to a political party that wants to force religious charter schools to close."
That doesn't mean the behavior of the company is political in the same direction? Am I taking crazy pills?
