I have the feeling that you just like to argue. I have already said want i need to say. The only thing that I will add is that it is entirely unrealistic to expect normal people to use PGP signed FOSS software. Their functionality and UX is way below paid software. And I have met way too many arrogant linux users. I still remember back in the day asking "how do I make 3D acceleration work on my radeon GPU" and linux guys were condescendingly answering "You don't need that". Yeah, good luck with that attitude.
