Using a compromised node for any crypto will give them your IP address. Thats just a fact of how the internet works. Monero is not unique in that fact.

What is unique about Monero is that they still had no clue how much Monero was being sent and to whom *despite* a user transacting through a compromised Chainalysis node.
They couldn't even definitively determine if that IP address was the one that sent that transaction.
