Your line of thinking is very narrow. You think your personal information is safe posting on FaceBook? Twitter? Instagram? How about FR? Notice there’s no SSL on FR. You think your conversations and transactions on this website are safe? You think your personal information isn’t being traded by your bank? Your brokerage firm? Your mortgage lender? How about the dealership where you bought your last car? Amazon? Grocery rewards clubs? How about your phone provider? Cable company?
If you think that the OS you use insulates you from your personal information being distributed and traded, you need to change your thinking. I’d trust a corporation like Microsoft with my personal information more than the open source community. Microsoft is the number one security company in the world. They also have a HELL of a lot more to lose by a breach than Slackware, Ubuntu, Mint, or any of the other flavors of Linux out there.
