I really don't give a shit about Microsoft but I have to warn those who have bought a computer running a recent version of Windows with Windows Update enabled that :

- Microsoft is unable to ship security updates, to a system that gets patched at least ten new holes every month. Do you trust guys like this ?

- Microsoft is ramping up their user privacy theft by doubling down on personal data capture in addition to purchasing companies whose only merit is to have built a personal data database (linkedin is one, but a number of others, think those calendar apps for instance).

Why isn't a freaking country sueing those guys to death already?

Are not governments supposed to enforce the law? Isn't the law written explicitely to make it a crime to steal personal user data and by doing so prevent any form of privacy ?

What will it take? to throw your smartphone or computer in the trash bin ?

Wisen up people ! Microsoft is NOT your friend !!
