Arbitration clauses inside a TOS are evil in my opinion.
I can definitely see the desire to stop a class action lawsuit that seems to punish the company and benefit only the attorneys, but in a TOS situation I would say it crosses the line.
In many non-evil (consumer friendly) jurisdictions any such clauses are invalid and not binding even if signed with blood in full consent, and only serve as decorative filler in agreement text.
California is not such a jurisdiction, apparently. Yet.
We the people can (and should) vote to change that.
