It will be interesting to see how this affects "toxic," deplatformed, and to some degree debanked (at least from PayPal and CC processors) entities, like the KiwiFarms. While this page is somewhat vague about the private/public status of the Fed: https://www.federalreserve.gov/faqs/about_14986.htm
it seems pretty well established that federally chartered corporations, like the USPS and Amtrak (e.g., https://en.wikipedia.org/wiki/Lebron_v._National_Railroad_Pa...), are bound by the first amendment, so theoretically the Fed should be as well.
That means the usual "it's a private corporation!" defense of corporate censorship is probably off the table.
