Therefore unless he has given permission to be listed as founder it is highly unethical and manipulative as well as an outright lie to claim that satoshi was a founder of the bitcoin foundation.
Unless you are Satoshi, or unless he has given permission for you to speak on his behalf, the bitcoin foundation has as much right to speak on his behalf as you do. Since you've already made it clear that you believe that you have the right to speak on his behalf, this would seem to imply that in your worldview, the bitcoin foundation ALSO has the right to speak on his behalf. Unless of course you are a hypocrite that believes that there are special rules that only apply to you, and not them.
Let Satoshi speak for himself. If he doesn't care enough to get involved in this disagreement, then why do you think it's important. Satoshi clearly doesn't think that "an innocent man's life might be in danger" over this, and is therefore ok with what the bitcoin foundation has chosen to say about his membership.
The onus is on the foundation to prove he was a founder.
No, it isn't. The onus is on you to prove that Satoshi doesn't want to be listed as a founder. Otherwise, you have no right to speak on his behalf.
If they can't provide such evidence then his name should be removed
If they wanted to do that, they already would have. How exactly do you intend to force them to do so? By creating another discussion thread in the bitcointalk.org disccusion forum? That didn't seem to work so well the few hundred times that other people tried it. Why would your rant be any more successful?
so that outsiders can see it as just a group rather than THE group created by THE man himself.
"THE man himself"? You do realize that Satoshi doesn't have any special super powers, right? He's not God or anything like that. He's just some guy (or group of people) that happen to have come up with a pretty decent way of handling distributed consensus and used it to determine what order transaction occur in. That's about it. He wasn't even a very great programmer, or great at cryptography. He made several programming mistakes, and made some questionable cryptography choices.
The fact that a decent programmer with some better than average knowledge about cryptography belongs to some private club shouldn't matter to anyone except those foolish enough to believe that celebrity is persuasive.
