Yet again, I see dissident right wing people on X are surprised when a Big Tech cancels someone off their service for political reasons.
Shopify had yeeted alt right people off before, notably cancelling merch stores after the Charlottesville riot in 2017.
DO NOT USE THEM, they are off limits to you. Yes, that means you will have to put some effort into your merch store. BOO HOO. Nothing resilient is ever easy.
Kanye cleared his entire store of all products except a single white shirt with a swastika for 20$, which meant he wasn't making them a dime anymore and likely influenced the decision like you said.
But yeah, look at how many guys get cancelled long after their prime. Neil Gaimen is a recent one and it took a decade of him being irrelevant for it to finally breach the surface instead of just sliding off his back like all the previous attempts. Cosby took 30+ years before anyone would hear it. You could go on and on.
The other end of that coin is that it mostly happens to guys who its beneficial to cancel for a lot of people. A random nobody dunking on Nick Fuentes during one of his retarded spiels is likely to get a lot of Leftie seals jumping to his store to give him money, which people will notice and repeat. And once this happens enough it becomes a tidal wave that can crush people who aren't stable enough (mentally or financially) to wait it out.
Even before clearing his store, he was selling sweatpants for $20; he used to sell them for hundreds of dollars each. I suspect something is fundamentally different now and he's not making much money before the stunt
I agree with everything else though
