The Ancap crowd and the fuck brainlet Sargon crowd really need to take a step back here and realize there are more important issues at hand then corporations deciding who they should deal with and the money stream of an ex applebees waiter.
To address the Ancaps first, what is going on here is a direct assault on the principles of a free and open market. Patreon has a near total monopoly on online persistant crowdfunding. The reason for this is not natural either. You see, online funding companies like Patreon are not the payment processor. That network is handled by the credit card companies, and for the internet more broadly transaction underwriters like PayPal's Stripe. There were competitors to Patreon, and virtually all of them were blocked by the payment processors because they "supported the funding of hate" or other such things Silicon Valley deemed problematic. This is anathema to a free market. It would be akin to trying to open a competitor to McDonalds across the street, and for McDonalds to then go to your beef suppliers and telling them to stop delivering you beef. You could be making the far superior burgers to McDonalds, you could have plenty of customers who WANT to buy your Burgers, but you go out of business anyway. Because McDonalds cut your supply chain.
Incidentally, that is very, VERY illegal in the United States. The problem is the laws involving these behaviors are over a century old and have not been updated to cover the digital space. Something Silicon Valley is ruthlessly exploiting.
As for the fuck Sargon crowd, you need seperate the principle from the man. You may think he's an idiot brainlet with an overly large platform. You may even disagree with him. That is fine. What is not fine however is for someone to be driven out of the political debate by the actions of colluding corporate powers controlled by an opposing political ideology. This is a dangerous precedent to allow to stand. You may hate that Carl will be the face of this, and the idea of Benjamin v. Patreon in the Supreme Court of the United States challenging the constitutionality of Section 230 of the communications decency act and the legality of online payment processors deplatforming "hateful political speech", but the truth is you don't often get to choose the time and place of the battle.
Ever since they deplatformed Alex Jones its been one "problematic" online pundit after another. This time though Silicon Valley may have really stepped in it, because unlike the other online pundits he is actually considered a major figure in recognized political party. We could argue whether or not UKIP is a meme or if Carl is actually important to it, but the fact stands that his membership and the use of his platforms to advance UKIP as a political party gives an extra layer of official status of Carl that even Alex Jones lacked. The fact that this is a US based company targeting an individual in another nation also lands this in Federal Court by default. And the only way this can be resolved is if Carl takes it all the way to the Supreme Court and gets them to strike down section 230 for being unconstitutionally vague, as well as to apply a smack down on Silicon Valleys manifest illegal collusion.
