I'd wonder if the existing amateur presence would make the bands hard to sell for "pollution risk". There's a lot of kit in circulation, and getting it off the market, including secondhand, would be difficult.
Yeah, they could blow a lot of time and money on FCC enforcement, but it feels like trying to unring a bell. As a telecom, would you be willing to pay for (for example) 148MHz on just the promise the existing users were displaced on paper? That doesn't mean much when some untrained/curious person finds kit at the Goodwill and tries it out in the middle of your service range.
Of course, obviously fight for every nanometre of spectrum, but that's probably a legit argument against reclassification: all they'd get is damaged goods of low resale value.
There are two issues with human rights.
One is selective enforcement. There are a long list of countries with abysmal human rights records, but it's too strategically convenient or economically essential to look the other way. Whrn was the last time they made a fuss about Jamal Khashoggi? Human rights only gets invoked when sabre-rattling is useful, not as a solid and consistent moral framework.
The other is that it's a "luxury product". Can every country support a modern human-rights model, or does it require a certain level of economic and political stability? It's hard to maintain rule of law amid active insurgency, or if you can't even deploy the bureaucratic state. Once you've gotten past that threshold, will both leaders and the broader population be eager to switch from the system that got them where they are? You've got to convince people that being able to write an anti-government op-ed is more important than security, or the price of eggs. This is a long term soft sell: berating countries for not measuring up to Western standards isn't going to get them to make that choice any faster.
