I don't know why this impacted your decision to turn off your node?
Polo is a U.S. exchange, they need to comply with U.S. law. It sucks that it happened so quickly, but I'd rather there be an exchange than none at all. I believe decentralized exchanges are coming, and when they do so people will be able to trade freely and anonymously.
Poloniex changing their rules certainly makes our short term direction cloudy, but if you check, there are a lot less sells than buys.
i was just frustrated (i turned the computer completely off

), the short to mid term future for monero has not been as cloudy as it is right now for a very long time. i dont know if i really belive in decentralized exchanges. Open transactions exists, yet no one really uses it. decentralized exchanges wont fill this gap for now. A quick and dirty unregulated, centralized exchange needs to pop up until then, somehow comparable to how cryptonodexchange did it, just in Tonga, Monaco, whatever

Well here's the thing(s).
1. Poloniex is not Monero and Monero is not Poloniex. All the exchanges doing this are affecting all the assets they trade. It's KYC/AML for Monero, NXT, DASH, ETC... The playing field is still level.
2. There are still ways to trade. XMR.to, Shapeshift, Coinomat. Combine these and other services and you will find a way to retain full anonymity I think.
3. Plus trading on Poloniex does not break the anonymity of Monero in any way! It just changes your relationship to Poloniex.
