The "End the FedNow!" merchandise is pretty clearly parody.
The stuff that just has the "FedNow" logo is borderline. I wonder why organizations do this, highlighting the logos of organizations they oppose. I have an EFF hoodie that says "National Security Agency" on the front and "Defund Big Brother" on the back, and I get questions all the time of "Do you work for the NSA?" and then have to turn around and show them the back. I wish parody apparel was always parody at a glance.
