I wonder, what is ICANN official position towards New.net and their 'alternate gTLDs'?

Looks like anyone can invent their 'private Internet', introducing their own root DNSes and any 'gTLDs' they only wish to create.

If these 'private Internets' continue to grow and multiply, the very basics of Internet will be ruined.

It is remarkable that many a registrar support both 'official' (ICANN-governed) and New.net's 'Internets'. That's weird, in my opinion.
