Simply put: no proof, no "case".

But, as I keep saying, if your aim is to make noncommercial criticism of a company, a .com address makes no logical sense.

To: Daniel, in relation to the remark, "a .com address makes no logical sense".

If there were a ".critic" or some other such TLD which clearly categorised noncommercial criticism, you may have a case. While ".org" is noncommercial, it suggests a nonprofit organisation of the given name, not criticism of a commercial entity with the given name. The ".com" address is about as good as it gets, since it is a commercial entity that is being criticised. There may be a case for using ".info", but we are now splitting hairs in a situation which does not involve split-hair precision. A domain name can't precisely describe the purpose to which it is put in all cases, and there is no established rule dictating that critics shall register such-and-such a domain.

Or, as I have said (less succinctly) elsewhere, when you choose to imbue TLDs with meaning, you only get so many good fits. Get used to it, or abandon the idea of meaningful TLDs.
