I am willing to accept that the WTS would not want to give Evans publicity because it would just get messy for them. But other than that, I would imagine that there are at least three or four GB members who would love to try to take him down, because he's gone at them many times in his videos. And if Evans is a raging narcissist, I can only imagine how bad it is with those guys. Evans didn't even get to 1,000 patrons; the GB has millions of admirers who believe that their words are coming almost directly from Jehovah.
They would risk giving him a publicity boost that he could never get on his own. I mean, people marvel over how much attention he is getting from the exJW community lately, but what did he need to do to get it? Have the details of his disastrous private live leaked online? Partly. Give everyone those sordid details himself in a long, rambling, insane livestream? Yep. Go nuts afterwards and expose himself as an unstable sociopath with delusions of grandeur? YES.
Why would the WTS even need to intervene at this point? I bet at least a couple of them, if they ever discussed Evans, predicted that he would eventually blow himself up. All they needed to do was ignore him. Anthony Morris has probably been buying more champagne recently, for all of the toasts they keep offering at their get-togethers now.
