Sure there might be other problems, but not that one.
What is the concrete problem DRK is having (in addition to constant trolling) now or in the future that is a direct result of the unfortunate launch?
Perpetual criticism that it is the fruit of a poison tree. Meaning either incompetence or fraud, and both are indeed poison to outsiders who dislike both and are structurally unable to distinguish them.
That does not mean zero success, but it will be an unnecessary burden to bear, and that's a tough obstacle in a brutally competitive market.
So the concrete and actual problem is FUD. Agreed pretty much.
