Never trust proprietary software you absolute mongoloid. Not proprietary operating systems, not proprietary web browsers, not proprietary communications software. And for all you gamer brainlets out there, no, you should not be trusting or even playing those proprietary videogames, either, they are almost certainly bundled with glowie spyware that monitors everything you do on your computer if you so much as run the game once. Even the firmware embedded in you device's microchips is not exempt. If it is proprietary, you can guarantee that that hardware is backdoored and the NSA is using it to spy on you.
