You are assuming that we know what "ruining .org" means for everyone. We don't.

From an investor's perspective "ruining .org" means the asset won't produce return on investment. From your or my perspective it may be something entirely different.

It depends on the economic benefit they can extract and get away with.

You can extract more value by squeezing the people who need it than by devaluing it by selling .org domains to scammers and phishers.

You can register a .org domain no matter what purpose you give to it. Scammers and phishers have always been able to buy .org domains.

Long-term? Yes. Short-term? Not necessarily. And it's a rare market entity that prefers long-term value over short-term gains.

You do both. As you squeeze it stops being viable for legitimate players.

Then the scammers dominate.

Because they will raise the prices enough that legitimate orgs don't want to pay it, so they'll be available.
