So I've been passive since this trash talking started.
I have zero coding skills and have been involved in neither voting nor developing BitcoinZ.

What I don't understand is how did you get screwed?
You accepted a job, you completed that job and got paid for it.
That job is not your property anymore. You got paid for it by BitcoinZ community. It's BitcoinZ property.

I'm a part-time photographer. I take pictures of a wedding and sell it to the couple who got wed. From now on, those photographs belong to them. I cannot just show up and demand them back. Or contact the police so they can break into their house and take all the photos from them.
ESPECIALLY if I was paid for it. Do you realize how ridiculous you sound?

By taking down the video, I see this as a theft of BitcoinZ property. Getting credit for something is ok if you didn't get paid. But you got paid. BitcoinZ community is not required to give you any credit at all.
You stole from everybody who has been donating to this project. Please move on. We don't need you here. Neither you nor your work.
