"just build your own platform"
The good news is that the continued censorship will fuel adoption of crypto and speed up the demise of parasitic middlemen who take a cut off every transaction

Most business owners do not have the technical ability, interest, or logistical overhead to actually accept "crypto" (or cash) without "parasitic middlemen". This is why Coinbase, BitGo, et al. are very successful in this area, and account for virtually all cryptocurrency commerce. The function of Coinbase or BitGo is not parasitic; no business wants to cope with the arduous requirements to be able to accept and store cryptocurrencies.
Remember, all that you have to do is make alt currencies inconvenient enough to use for normal payment needs, and this will discourage people from getting involved. Lower participation deprives the alt economy of goods, services, and the ability to exchange currency for "real" cash.
That doesn't mean that crypto is totally useless, just pointing out that there is not a technical "silver bullet" solution to this problem. Technical solutions must be part of the answer, but these must be backed by political force.
