Tough questions. I think blocking users is almost never a great solution, especially on BTC/LN products (even though as a company you can do it, opposed to the otherwise censorship resistent nature of the protocols). You also would have collateral damage by blocking people not in support of what's happening. Plus it's a little like the US weaponizing the dollar and the longterm consequences of it (loss of trust)

Informing people is a softer way, but that's more up to how political one wants to get as a company.
