This seems like an agitator trying to raise a fuss, not a "whistleblower" (I guess maybe that's how the term is used now). I'd encourage people to read the surrounding tweets, he looks like someone who wants to be outraged about something more than a brave soul calling out some malfeasance.

That aside, if this money is for facilitating sessions, as another comment implies, it is perfectly reasonable. The facilitator has to prepare, follow up, etc. and is presenting to a group. I've done these kind of sessions and that rate is not high. The per hour of facilitation time is a meaningless way to look at it. For all I know, maybe there is something untoward going on, but the usual racial outrage we see in the tweets, and the inflammatory, clickbait headline certainly dont make any kind of case
