There isn't any comparison to Microsoft as far as I can see who refuse to open their operating system to improvements by us ...their users.
Ooooh my friend... it would be a mess if everyone selfproclaimed "programmer" tried to dig our OS... no, no, no... I don't want to see anyone touches our OS, no matter how many "holes" it has... admit it or not, Microsoft is taking good care of it... no one ever made any harm to my system and it will not, I'm assuring you my friend. Those selfproclaimed programers have good oportunity to play with million others open source applications on the market, there is really no need to dig through the Windows. Maybe, they would bring some improvements, actualy that's for sure, but on the other hand, I'm pretty sure it would open new security "holes" in our base...
I'm really happy things look like right now...
Cheers !
