Could someone post a one or two paragraph TL;DR for people in here who don't have the time right now to read the entire piece? You can reasonably assume we do already a) know what tcrypt is, and b) know about the discontinuation annoucement almost two years ago. May the upvotes then be with you.
He eventually started his pharmaceutical business and made hundreds of millions of dollars. According to sources, he became gradually "darker" as he got more money, including allegations he had people killed. And then recently he was arrested by the DEA.
The article got most of its information by a supposed relative - the reporter is convinced it's legitimate because of how much they know about Paul and their access to documents a non-family member is unlikely to have.
The other interesting new information is that his biological mother (edit: grandmother) is the wife of a US senator, but there's nothing to really collaborate that other than the word of the anonymous soruce.
There is no new information about the discontinuation of TC in this article. The article says that Paul disappeared from the crypto community (at least, under his own name) at about the time he started his pharma company (2004), but implied that he had worked on TC for the decade leading up to 2004. The anonymous source also said he "switched" to the pill selling, perhaps suggesting he left the TC project around that time in 2004.
If I had to guess, whoever was funding the TC developers stopped funding them. And the developers decided to move on with their lives, having worked on it for 15+ years, and possibly largely only doing so because they got paid. The "TrueCrypt is not secure" message was probably to imply that a lack of updates wasn't because they were confident they weren't needed, but rather because it was no longer maintained.
