https://poloniex.com/terms/After proceedings against MtGox and now BTC-e, looks like Polo got their legal team together to cover their asses. In summary, if they ever go down or lose funds due to hacks:
1. You can't hold them responsible.
2. You waive your legal rights to class action lawsuits. So no MtGox style claims. You're on your own.
2. You may only file legal claims from Massachusetts.
I remember they had an update of their ToU not long ago, maybe a year or less (edit: it was 2015). As far as i remember those points you mention (1 and 2) were already in the text then, so it's not like they added it only now. What exactly they did change i don't know. I would like to see a side by side comparison between the current ToU and the previous version so we could see the exact changes they made.
Some toxic hateful people who thrive on chaos like to spread rumors like this and then enjoy watching the mayhem they cause. Anyone with half a brain can see right through the fallacies in their posts.
Of course it's good to be cautious, especially if you have large sums of money on an exchange, but it's quite another thing to see some problem (long wait times) and then jump to a ridiculous conclusion (insolvency).
