Nobody loves them, but they're important in this case to help parralyzed humans maybe with ALS or some other disease communicate with loved ones
Where it gets funky though is trying to quantify that to an extent: how many monkey disfigurements is worth fixing one human disfigurement? Ten? A thousand?
How many chimps would you blind in order to prevent humans being blinded by the latest lash extension cosmetic?
Is it even controversial that yes, of course they are?
I mean, Boeing and the FAA kept 737 MAX's in the air after brown people died in the first crash when we all know they'd have grounded them if it was a crash in Kansas. We value human lives differently let alone animals.

None. But I'd blind as many as are needed to trial human eye transplants, for example.
