To make that work, everyone would have to agree on the domain to move to, and everyone would have to move more or less together. And the new TLD would need to have its hands meticulously tied to prevent it from pulling the same thing in future.

In other words, mission accomplished - for the big-money interests that want to drive such tawdry "non-profit" nonsense to the fringes of the web and allow a clearer run for the good, healthy pursuit of $$$.
