I still don't know how that dude makes money. People use my software multiple times a day, so the nag is quite annoying. I need WinRar once in a few months, maybe.
Though if my memory servers me right one time I bought it for a staff of the site which has.. quite dubious legal position by hosting the abandonware. Of course it was technically a breach of contract because there were multiple people who could use it, it was still one legal license more.
