Yes, I believe this, too. He killed his company and his software not focusing on the VistaDB strength being an excellent website database, Xcopy deployable and first of all running in Medium Trust on shared hosting servers.
But he wanted simply to high subscription fees and concentrated on implementing his paranoid licensing system to enforce it. No wonder that, as he writes himself, the revenues decreased constantly. Many developers would be ready to pay yearly about $100 without problems but not the amounts he wanted. So his company collapsing is his doing and not caused by wrong behavior of other people (software developer in this case).
