This whole discussion is basically a field demanding that their field be preserved for them alone to discover. No competition allowed besides the monks of mathematics.
You can invent whatever fantasy you like. I hope more honest people will read the letter (from the fields medalists and other endorsers) and consider it on its merits.
Spot on. They now feel threatened that there's multiple challengers to their intellectual monopoly. This is their "whaaahhh... whaaahhhh... private company bad, now," but where OK when Halliburton, Boeing, General Dynamics, Monsanto, Open Society Foundation, Tides Foundation and many other shitty and scummy private and so-called "non-profit" entities were funding their shit. Now their entire business model is changing. Is not that it'll completely collapse, it's just changing and they are throwing a bitchy fit.
Shouldn't the AI companies know by now that all mathematical knowledge belongs to the mathematical community? Hopefully this letter knocks some sense into them.
