Actually the idea is brilliant. If you can demonstrate empirically that meat from happy pigs tastes better, now you have the beginnings of a commercial case for raising the pigs ethically, which has the potential to drive far more improvement in livestock well-being than a million Internet virtue signals about animal cruelty.
I agree with you, my concern is about what happens if the data doesn't point in that direction (tortured pigs taste the same) or if the market just accepts a trade-off (less quality for less price) disregarding their suffering.
I believe technology is inexorable and we'll just have to see what happens next.
