Well, that's what you can expect from proprietary corporations and proprietary software: they always try to fool their customers and treating them like retards. That's one of major reasons to stay away from these as far as you can. I'm personally consider proprietary software untrusted by default. Availability of source is a good indication that program vendor respects fair play. Sure, it's dumb to release sources if you backdoored and trojanized something: this increases chance to get caught and allows to uncloak this treason faster.
