Well, apparently people from stopgame that actually DID the voiceover using their own player without any ads afaik, and they wage war against those people who simply try to get money from actual content creators, by placing claims on EVERYTHING they can, running the channel that placed a claim on you. In basic words - people behind voiceover didnt do that, neither the site that they work with.
Serves them right, and dont be upset, please.
And i'd guess 70/30 splits are fine, you getting more, ofc. But i doubt that it will ever happen.
UPD: Looked up into everything and talked to people to clarify things.
