I don't like the deplatforming craze of the last few years, but getting banned from Coinbase is pretty mild. This isn't like getting banned from Paypal or Facebook, which permanently cuts off your options. It's more like getting banned from one particular web host, at which point you just sign up with another and keep going like nothing happened.
I'd be worried if I thought every exchange would do this, but this area is highly competitive and filled with small businesses that are either run by libertarians (who would defend Milo), or who want to benefit from the free publicity.
