Like a comment early on said, being a real translator and seeing a work get translated by mtl, or worse, generative ai, really makes you not want to do it.
I mean, they've already shown their utter lack of care for the hard work of translating by using the slop bot that's been trained on stolen data and books the ai companies got from pirate sites rather than buying them. You're already fighting against that in your real job, why fight them in your unpaid hobby too? You're too busy paying your increasing electric bill from the ai companies refusing to pay the power company because it's "discrimination" to expect them to pay anything for their database guzzling up the power equivalent of a large city right outside your small town in the countryside.
And ofc Mangadex is on the ai side. They're fucking crypto bros, which are always part of the "ai will save the world" cult.
