I don't think it was intended to be a scam. The founder raised too much capital on the back of massively inflated expectations.
They couldn't deliver (didn't one of the technical team commit suicide in despair over this?) and rather than doing the honest thing and returning the capital, they've ended up creating a Kafkaesque web of shadows and lies.
The fundamental issue is overfunding, and it is not limited to this one company, which is why we're in bubble territory once again.
