The CEO is right out in the forefront of this one. It would be easy to track him down if this were an exit scam. This was a high profile project I am thinking the authorities would track him down in short order.
If that was the case, most scams wouldn't exist. The reality is that most people involved with exit scams, insider trading fiascos, etc. are busted, but they still try to get away with being crooked because of greed. That's the reality of man in a nutshell. Instead of just having Adam claim during interviews that insiders/team members didn't dump tokens prior to and during the announcement, they should have provided proof. It's the blockchain for Christ's sake. Everything is there and its the best way to clear your name. Of course they didn't do that.
Watch the video I mentioned above to see the funky volume activity of DGTX tokens before and during the announcement time.
