now you don't want him to have your interview in is playlist anymore, and ASKING HIM TO TAKE IT DOWN IS NOT AN OPTION, could you Report it to youtube ... Is that possible?
I don't think the person interviewed has any legal rights to the video unless they agreed something before-hand, that it would only be used for a limited time or that they had control to be able to pull it.
This needs to be a lesson for people - don't go giving away your life story to someone else to make money off, with no control to remove it if that person turns out to be living a lifestyle that you don't want to be associated with.
There's often not much that can be done in hindsight, other than try to have public opinion force him to remove it (but we know he doesn't really worry about his public image).
His followers seem to fall into two categories. Those whose life-decisions are similar: fornicators, adulterers, misappropriation; or what have you. Those who think that anyone who rants about Witness culture is on their side and that any moral fault should be overlooked as long as he says what they want to hear.
I've seen this a lot in exJWism over the years. There are a lot of people who are kicked out of the WTS for damn good reason, and then like a jilted lover they try to tear the WTS down as though doing so would validate their own poor behavior. Of course it doesn't, but they end up being cheerleaders of every radical "activist" who is willing to shout or throw mud in the WTS direction.
The best lesson / reminder in all of this: just because someone else also left the WTS doesn't mean they are a nice person or that you need to have them be your friend. You just had some vaguely common shared past, that's all.
Imagine you left a company because you didn't like how they treated you, would you want to pal around with some nut who was fired for stealing from the same place, that wanted to vandalize their premises? You really don't have anything in common at all, don't let them fool you into believing you do and that you have some duty to support them or that doing so will provide you any kind of "revenge" at all.
