Hashrate be damned if the ISPs receive order to cut every connection that syncs a node. It's a game of whack a mole but trivial to implement. We won't be syncing over Tor, that's for sure.

If the goal was to cripple the network, this is the simple stupid solution. The Lightning Network is almost completely custodial, it disappears instantly when AWS, Google, Hetzner, Alibaba shut down the accounts that run nodes.

This is always on the table, better let the greedy bastards who are on postions to give these kinds of orders play the stacking game.
