Not sure if the video said it was from him or not. It’s been taken down, so I can’t check, but I don’t think it ever made that claim. Someone just noticed it sounded the same as Jeff.
It’s copyright because they had to have fed the model with voice data from Jeff’s videos.
Well in this case they used his likeness and brand to appear more legitimate and make money. So I’d argue this is trademark (even if not registered) so a legitimate complaint.
I don’t believe in “copyright” for a voice. See for example impersonators. But in this case it’s a deliberate deception which is pretty simple.
I don’t believe in intellectual property at all and think it is a form of theft, to deprive others from common knowledge or information just to seek rent. In case of patents I equate it even to aiding in genocide, since most advances in more energy efficiency use are patented and exploited for profit and slowing down adaptation. Without exhaustive attempts to try other systems to pay creators, copyright law is a moral abomination. That is a philosophical or ethical argument, not a legal one.
