Thoughts on Robert Spenser, who runs jihadiwatch.org, having his Patreon account shut down, not for violating the ToS, but at the request of Mastercard? He seems to have some pretty nuanced, moderate views of Muslims and Islam, and really only takes issues with the extremists.
Tim Pool speculates that perhaps an Islamic country doesn't like Spener's opinions and told Mastercard to shut him down or risk all operations in that country. Faced with losing a lot of money, the easy choice was to squash one man's ability to conduct business and get his message out.
With the world moving towards e-commerce (we currently have a thread about businesses no longer accepting cash), large multinational corporations will wield even more power, to shut down and silence individuals and make it impossible for them to put food on the table let alone get their message out. They would be all too happy to see these people forced to give up their work and accept 9-5 jobs - less time and energy to get out those opinions. But don't rock the boat too much on your free time or they will go to your wage-slave employer and tell him to get rid of you or risk losing Mastercard's business. It's their company, they can do what they want.
