Motivations:
* This issue of .org being sold for profit
* The fact that OpenNIC had to rename their TLD domains (e.g. .free to .libre) when ICANN created a colliding .free domain, demonstrating clearly that they are not peers.
Internet technologies such as browsers and operating systems should recognize ICANN and OpenNIC roots as peers, with DNSSEC to both. Should ICANN decide to create a .libre domain, existing browsers and operating systems should consider it a DNS attack and not recognize it. I think an organization like Mozilla ought to (1) flesh out any technical challenges, (2) support OpenNIC and (3) push for this.
