The guy did directly fund the aforementioned Nazis...

Yup. I wouldn't have hated it if they said they can't discriminate against customers as that'd require some surveillance and go counter to the project, but to still condemn nazis because it's appalling. But refusing to condemn nazis in the name of privacy is absurd. Do they think if nazis get in power they'll look back at this and let us have privacy?

More cynically they probably believe this is a market and as a business they need to increase their profits even if it means, as you said, becoming a nazi bar. But whether they see it or not, they're encouraging political forces that seek to destroy their whole business, so even cynically they should oppose this.
