It costs ~$200,000 to apply for a TLD, and there's an ongoing renewal cost in the tens of thousands of USD.
Also, who is paying for the reduced fee, administrative and infra costs? And have you actually submitted gTLD application, or are you trying to crowdfund? Unclear to me.
90+% of people who would be willing to sponsor this stuff will go "hmm, I wonder where they've taken their money from, not us I guess." Not everybody reads comments, even fewer post ones of their own.
Being on the front of HN is a great opportunity, I'm afraid you haven't used yours as well as you possibly could.
