Hey, I’m only saying this on the off chance that it is helpful. I’m not sure if you are aware, but your question comes off as a little aggressive.
Partly because it’s such a diversion from the topic on hand. In my experience, such diversions are often made by people with more passionate or militantly-held opinions.
Whenever I catch myself “needing” someome to change their view, I know I’ve gotten off track and should gently tend to whatever is going on under the hood. I don’t really want my well-being or peace of mind to depend on the miscellaneous viewpoints of others.
(a) You've misunderstood. It isn't "10 people ever": it's "10 people often". Unless you're requesting an ongoing relationship, the answer is "no".
(b) What is trust? Examine the nature of trust, and you will see why "you can trust FOSS" is a truer statement than "you can trust Microsoft software". (Neither are true, in my opinion, but I have a higher standard for "trust".)
I happen to trust Microsoft software more than FOSS en-masse. I think Microsoft FOSS software is more trustworthy than either, for instance I have high confidence in VS Code as an editor. It helps that I've read through most of it's code and authored a good chunk of it as well.
