As most of you already know, BillP sold WinPatrol a few years ago, having determined that he was no longer able to give it the full time attention he believed it deserved. http://en.community.dell.com/support-forums/virus-spyware/f/3522/t/19582562
He continued his career, part-time, as an "independent developer". However, continued health issues have made him realize he won't be able to continue working even in this limited capacity. As such, he has officially announced his retirement.
We are sorry to hear of his ongoing health (and related financial) problems... and wish him the best in his retirement.
