i don't think that on an individual level you will get any wide-spread fallout from stuff like this, mainly because i don't think the majority of people who read translations will remember the names of who actually did it. but that kind of defaming sometimes gets generalised, and in our case here it doesn't end up being 'tres' translation' or 'hito's translation', but 'the tls translation'. so any attempts to discredit one person's work ends up affecting everyone who works on the site. so if that notion that you can't trust 'tls translations' because they're dodgy liars and they knifed a granny in the street once to take her old lady hat, that affects everyone. it's mainly the super hardcore types who are going to remember specific names.
that said, defamation like that only really works if it gets wider traction. and i don't know if ltd stuff will get that sort of reach, unless particularly assy jerks just start saying 'you can't trust them' without context that lets people know it's because they're upset about shipping dramas. but everyone else who isn't deep into this (lucky) probably isn't doing to pay it much heed or even realise.
that said, i think you can still put something out on a contentious issue if you're confident enough with your work and if criticism amounts to basically 'i don't like it so it's wrong' then fuck that noise. (or the really weird ass objections like the invisible space in 'koi [??mystery zone??] bito' or 'you didn't acknowledge the ku' and all those terrible things, don't make me remember the terrible things)
you will always get the people who disregard you and try to write you off completely because they don't like what you said, so there's not much you can do about it
but like splintered said, there hasn't been anything new as far as this stuff goes for a long time so i think it would risk just treading old ground but in a new format. i think with the remake now official there could be a market (???) for retrospective videos, maybe like offering explanations of parts of the story that were vague or confusing (i always thought the idea of doing a video covering the jenova project but in the style of a shinra report would be fun).
i don't think i ever noticed his ear being popped back before and i don't know why because i look at that like 15 times every time i see it
