This isn't a free speech issue, or even a political issue. Patreon barred Milo Y from using their platform because his hateful rhetoric violates their terms of service. Ditto Carl Benjamin. Businesses have the right to draft and enforce terms of service which govern their subscribers behavior while using their platform. They have the right to bar individuals whose behavior violates those terms.

It makes me laugh when a group that insists 'the free hand of the market' should govern business transactions, suddenly cries foul when that hand smacks them on the ass. This is also another example of the party of personal responsibility attempting to blame others for the consequences of their own deliberate actions.
