Agreed, if mail is important, but for those of us that have a million little freesites with no need (or desire) for surfers to contact us it's not so high on the list of priorities.

They can't really hold it hostage since you can just change the name servers at your registrar. (Which is why you should never let your webhost register domains for you)
Granted this may take a little longer to propagate than a quick change to your zone file.
It does seem strange that a major registrar uses 4 DNS IPs from within the same block, meaning same route, same D/C, possibly even same server. That's an elementary mistake.
