I believe Collison's argument is that certain organizations affiliated with ex-President Trump should have been and were suspended from direct use of the Stripe API for "incitement to violence" in the time surrounding the certification of Electors by the U.S. Congress, https://en.wikipedia.org/wiki/2021_storming_of_the_United_St.... But other organizations that were allied in some way with Trump were still able to use the API. So in effect, the Trump-related organizations could use the API indirectly.
With that reasoning, shouldn't there also be organizations on the left in the United States, which is defined as the progressive / liberal / socialist part of the political spectrum, that should have received the same treatment during the period of the George Floyd Protests, https://en.wikipedia.org/wiki/George_Floyd_protests?
