Consider that the majority of people aren't familiar with RFC 1591 -- I think that would nullify any argument that the use of a country code TLD is "misleading".

Numerous countries in fact permit and promote international registration of their ccTLDs as a product for creative domain names, including .co (Colombia), .cc (Cocos islands), .fm (Federated States of Micronesia), and .it (Italy).

And importantly, conventions change, and RFCs are a starting point for an evolving set of standards. .net isn't limited to "only the computers of network providers" as RFC 1591 states. Is everyone with a .net domain doing something incorrect?
