There is a lot of pushback against the new ToS, specifically the arbitration clause. The fact that the vast majority of people will not opt out due to not sending in snail mail within the first 30 days of notification is incredibly problematic. This move is greatly reducing the trust many people have in the company. SE staff have clearly noticed, but the changes they suggest do little to remedy the situation. Is there any chance that this clause will be removed, given all the community feedback?
To quote another user succinctly pointing out why we are all worried:
The practical function of an arbitration clause in a clickwrap terms of service document is to immunize the company (Stack Exchange, in this case) from class-action lawsuits. Given that all community use of the SE website family involves no money changing hands either way, the only reason we should expect anyone to file a class-action lawsuit against Stack Exchange is if you commit some sort of massive privacy violation or copyright infringement.
