> If you select who you provide services to based on their ideology

Nobody in the world DOES NOT do this. If an advertiser takes down their ads from a website because that website is spreading white supremacy then they are doing just the same. As they should.

Also where do they claim they are "just an infrastructure provider"? They clearly say throughout that they provide services for anti-racist/anti-sexist/etc orgs that can't afford to do it themselves.

They do not make a profit. They are not a company. They are literally a group of friends helping orgs out.
