Replying to myself because this comment is on a different topic: the arguments about deplatforming in the linked page are quite frankly ridiculous and are unlikely to succeed, whether made in court or in arbitration.

Patrons in patreon do not have a direct contractual relationship with the projects they sponsor, so there can be no tortious interference of contact.

The cases are simply a gambit that patreon will settle and let these racists back on the platform rather than pay the costs of arbitration.
