I don’t really fully understand your question so I’m sorry if this reply isn’t what you’re asking.
The reason why fan-translator get sue isn’t persay the translation itself that is illegal but because it’s a reupload of the entire manga. Most mangaka story are payed per chapter even in raw so to translate and post it means to reupload the entire chapter for free, hence mangaka and artist make no money. Same with company when it’s licensed, it’s not much about the translation itself but the company can’t be having a fan translation out there because it takes away profit from them.
I know that some people might find me stupid for asking this question.
Can't they just use the still-on-going "outsourced" translation works as materials?
Many times, we could find pro-level fan-translated works on the web,
however those publishing companies then licensed some pieces, and deliver than cease-and-desist notice to those fan-translator to stop their "voluntary work",
and start over from scratch, instead of making a deal with that person to...
let's say to use their already-done works as official stuff and only needing a bit of editing, and pay them. Or let that person continue their work but put some restriction on distribution thingy.
Heck, even some officially translated stuff I had read had way more inconsistencies than fan-worked one.
