Patreon's deplatforming policies are capricious and draconian because they have to keep financial partners happy, and the policies of those partners are capricious and draconian. Those with enough social media and commercial power can deal (in fact if TFA is believed it appears they can actually steer the machine of injustice). The author of TFA cannot deal, which is the entire point of TFA. We always knew in our hearts that "twitter as help desk" was unjust at some level. This is a concrete example of that.
[EDIT:] Now that I've read to the end of TFA, she buried the lede! This woman has been subject to so much shitty behavior! She was the third customer of a Patreon competitor, "SubscribeStar", and one of their largest customers, so the bastards just shut down the entire site. Now it appears that it's back up: https://www.subscribestar.com/posts/7863
