Why no trust

Some of us working in IT for a long time.
We have not forgotten big evil Microsoft. The same company that was behind the SCO Lawsuit against Linux and called open source cancer.
It actively follows a policy of Embrace, Extend, Extinguish. 
Microsoft is also known for its abuse of patents (see Netscape and Microsoft is generating $2 billion per year in revenue from Android patent royalties) and the recent Windows 10 Telemetry privacy issues. The list is endless.

One should be very cautious about trusting company that has a strong history of abuse towards open source communities and Linux operating system.

No trust aslo aplies for different and/or same reasons to the other 5 of the big 6 : Google Apple Amazon Facebook
