Trust is an empirically justified confidence, that means it is basing on a collection of earlier experiences that showed satisfying results from the point of view of the perosn spending the trust.
Microsoft has no such record with me, and the ways in which they try to sneak GWX onto my W7 system even when I deliberately said No and tailored my defences accordingly, has - due to the repeated efforts of theirs to infiltrate my system and to alter my system settings to open a gate for them - in fact formed a full bag of utmost negative experiences that have written MISTRUST all over them. It is the result of their doings. Cheat your customers, and get recognized as a cheater. No surprise there.
To read about how they also auto-reset privacy protection settings on machines with W10 whenever they send an update they decided the user should betatest them for them, no matter his likes or dislikes, is anothe reason why MS does not deserve to be trusted. A company that does not take the customer's No for a No, and instead does what it wants even when violating the explicit will of the system owner, deserves no trust. They violate the explicit will of me, the owner of my computer? They are out. Period. After all, its my property, not theirs.
I have drawn the consequences and have abandoned MS largely, almost completely, only maintain a gaming HD with W7, but do EVERYTHING else from a different Linux HD. When I update my PC in the forseeable future, I will get two systems infact: one gaming rig, if needed with W10, that is only used for launching games: if that data is interesting for them, so shall be it, it means nothing - and I mostly play offline anyway - ; and one laptop with Linux for any other task, surfing, online-shopping, work, data archives and so forth. In other words: all data they do or do not collect from me, is only about what games I play. They get no profiling data,. no emai,.a dresses, no nothing beyond that. Nothing. I do not even feel comfortable anymore to have MS and Linux residing on two difgferent HDs in one PC tower anymore. Trust lost is trust lost completely.
I do not tolerate MS being able to dictate the conditions under which i have to "trust" them. As far as I am concerned, they have shot themselves out of my life's orbit. And I am making sure neither their services nor any of their OS nor any of their software will ever return.
I may sound a bit old school, but the very moment some stranger adresses me with telling me that I could or should trust him, is the moment when my alarm bell comes to life. Trust is not spend in advance (that is hoping for the best when taking an uncalculatable or unpredictable risk), but needs to be deserved. And MS does not deserve it, but does deserve utmost mistrust. The record is clear and strong.
People using cloud services for sensitive, wokr-related or personal data that allows to profile them, I cannot help. I you refuse to hear the shot even when the pistol ,is fired right beside your ear, you're a hopeless case. I do not even touch onto the added problem of that storage servers usually are located in the US and thus fall under US jurisdiction and NSA espionage policies.
I recommend to maintain a regular checking of this, twice or three times per week, and especially when the patching Tuesday of horror is around:
