Agreed that they are not a pharmaceutical company, but the Phase 3 trial is being sponsored by MAPS PBC which is the for-profit subsidiary and I assume has some sort of revenue motive.
Here's what Rick Doblin, the founder of MAPS had to say about this:
"MAPS has started the MAPS Public Benefit Corporation, which is for-profit corporation. It's 100% owned by the non-profit, but still we have a for-profit arm, and the goal of that is to sell MDMA at a profit and then whatever the profits are to fuel more research and more public education."[1]
