There’s definitely a chance, but it’s a big risk to their business.

I don’t see it as a large threat (especially since it would require coordination and cooperation between the United States and China) but ultimately the only thing which mitigates this completely right now is the fee based model and the credible threat to fork which would render all mining equipment worthless.

Future improvements like having independent block template generation could make censorship risk even lower, but ultimately right now the most likely risk is that certain transactions would have to wait an extra cycle or two to make it in a block.

I agree that we cannot become complacent.
