What do you do when somebody attempts to take all the credit for your creation? I basically got my own Winklevoss that tries to take all the credit for my success. His own invention is utter crap btw. But mine he says 'its only good because of him, you wouldve never done blah blah w/out me'. It is the most pathetic thing I ever experienced. Why the hell won't they just go away?
Does he own any rights to it? Do you have any kind of contract with him?
If no, then tell him to fuck off and stop caring about what plebs think of you.
There's a reason liberals think that the rich are evil, even though the rich give more to charity than liberals make their entire lives, and it's because the rich give zero fucks about what poor people think of them.
I've dealt with this in a number of ways. Most recently in a business ownership/direction dispute. It turned pretty nasty, almost what I felt was parasitic in a way towards the end.
Anyhow, I decided to cut all ties abruptly without notice. I felt it should be self explanatory to them and if it wasn't, that was their problem. Everything to do with what it was we were working on/with/for. The nonsense continued with the 'he'd have nothing without me!' line in the mutual circles we ran in for what seemed like forever (probably to this day). The important part is that it was out of earshot, at least directly - freeing me to focus on what needed to be done.
I made it absolutely clear to everyone I was working with where I stood by saying calmly but firmly "I don't care what he/they think, say or do. We're moving forward. Period and that's that. If what I just said is in any way unclear, ask your questions now." There weren't any questions.
By the time I had a free moment to look back and see what became of them, I didn't give enough of a shit to even bother.
TL;DR Cut ties, block it out and focus on what youre doing
