One could argue that 'politically neutral' could also be a policy they apply to their employees at all levels; i.e. if everyone gets along at the office and does their job, that's really all that matters.

If anything, respecting an employee's personal life privacy seems fairly in-line with the values one would want in a privacy-focused VPN company.

"We have worked extremely hard to ensure that your internet browsing cannot be retrieved by the police, even with a warrant, and that you can be anonymous online" is not at all "politically neutral"

Like, I agree with and support their politics, but that doesn't make something politically neutral.

What evidence do you have that the company is not politically neutral?

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.

That doesn't mean the behavior of the company is political in the same direction? Am I taking crazy pills?

You're surprised the co-founder of a privacy company is advocating that a countries membership should be ... private?

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."
