I un-installed WinPatrol (Plus? Pro? yeah I paid) last spring after switching to Comodo Internet Security Premium but I still subscribe to Bill's RSS feed and yes he's a good guy, and I wish him well.
I can imagine thought that like a lot of shareware authors, he grows weary of support, support, support, and endless updates and hopes to find a way out.
Congrats "A Guy" on your 15,000 post! Geez only a year and a half--you do this full-time???
