The problem with keeping localizers on a leash is you have to be fluently bilingual to vet their work properly. Lots of places won't just have someone with that talent just sitting around to check their contractor's work. You need to be able to trust their work otherwise.

But Western localizers have made it impossible to trust any of them you don't know personally. And with all the constant backbiting and blacklisting even the companies you do think you can trust right now can't be trusted next year.
