I mean if they really did that there would likely be numerous paths to successfully sue the private equity company now controlling the .org TLD. Basic consumer protection laws require, for example, that buyers of like kind be charged the same price. I think that law applies to physical goods and commodities, but there is an argument to be made that domain registration is not as much of a service as it is a commodity loaning program. Another avenue could potentially be predatory pricing and price gouging laws. IANAL but I'm sure there are many, many things they could cite in a civil suit to stop such blatant ripoff schemes. In fact, I think if they did gouge them so obviously and in such a targeted fashion, it would probably be a great case for getting them torn apart under antitrust law since there is literally nowhere else you can register a .org TLD.

They could maybe add a mandatory arbitration agreement for future domain renewals? And then do this.
