You have to keep in mind that a dev only dislike button doesn't need translation, that even someone like the director can see a dev post on the english forum. The non-english speakers will then wonder what's up with that post and why it is so hated. This will lead to a need to know what's going on and help spead the information. This goes both ways too, plenty of people wander around the JP forums to see what's up, We too would be able to see a dev post over there that's been inundated with dislikes and wonder what's up.
