There are quite a few things I don't agree with tptacek about. But this is just the latest of a long series of hijack attempts for this namespace (the Internet's DNS hierarchy) and it's about time people learned that can't work.

Successful namespace hijacks rely on overwhelming numbers. You need to have so many people using your hijacked namespace that you've got way more people who do not even know that it's a hijack but are using it anyway than the existing administrators had total engagement so that it's pointless to argue with you.

Handshake can't get there from here, most of the world now uses the DNS hierarchy. This was a fool's errand. Carving themselves out a niche might have been possible, if they had been content with a niche but it's clear that their financial motives dictated they try for the impossible instead.
