From their policies page (https://help.riseup.net/about-us/political-principles/ https://help.riseup.net/about-us/political-principles/), the Riseup Collective makes it clear that they are a radical left-wing organisation. "We ... [provide] ... communication and computer resources to allies engaged in struggles against capitalism and other forms of oppression." I personally don't agree with their viewpoint. However, I also don't understand the belief that they should be a platform for contrary viewpoints. They're not Wikipedia.
