Quick question about pools and EIP1559

My pool, flexpool, is apparently against it. Without getting into a debate about 1559, I will just say I'm not worried about it, and I want to carry on mining after it happens. Do I have to do anything?

My understanding: EIP passes or fails based on a vote by the people who hold ethereum, so by staying on flexpool I am essentially voting against it, but it seems clear that it is going to happen so it's harmless.

I was reading about miner rebellions and I just wanted to make sure I wasn't going to end up mining on a competing chain or something.
