I definitely agree with your stance that we should exclude people from things because it's inconvenient. This is why I don't support accessibility measures in any domain.
I don't even understand what your point is? Wikipedia doesn't have to pay fees to accept crypto? They could keep other payment options too, no one said credit cards should not be allowed. They could just provide the address for the centralised exchange and sell it for cash with minimal problems.
What I'm finding out is that people have a bad case of Dunning-Kruger when it comes to crypto and it's usually privileged Westerners who don't care if other people are included or not. Just straight up racists.
Your rant is not contrarian for Western imperialists who don't want another financial system competing with their current hegemony.
That's why crypto is hated by Westerners while most others have neutral to positive opinions of it generally.
And the transaction fees argument and time needed for confirmation doesn't even make sense? Wikipedia doesn't need to pay any fees to accept crypto and it's not like they're a business which needs the money a second after the transaction. Even if they did need it that quickly, there are plenty of choices in crypto that settle much faster than Bitcoin, which they used.
