By the way, every contract ICANN signs with registries has a clause like 8.5 in the .com contract:
In other words, you don't even have standing to sue ICANN or VeriSign. You don't have direct contractual relations with them. You have to rely upon ICANN to watch out for your interests, and ICANN is trying desperately to get away from US government oversight to be independent (and thus unaccountable). Go to Guidestar.org and check out ICANN's IRS Form 990 filings -- their staff compensation has gone wild. Their motivations are certainly far different from registrants who are looking for predictable low cost pricing of their domains.
