I use GMail and Android. My job makes me use MSTeams, but I would've never used it if I had a choice. I probably use random bits of code contributed by both big companies to various programs on Linux... but this is about it. Also, the reason for me to use GMail is that I want to stick with the same email address, and migrating from GMail would've made it very painful. I use Android because the alternative is to use iPhone, which is even worse. If a free alternative becomes more realistic to use, I'll switch in a heartbeat. I worked for Google (through acquisition), and I know people who worked for Microsoft. I'd never apply to work for Microsoft. At least based on the impression I've received from people who work there. Of course, there are plenty of businesses Microsoft owns but doesn't actually "run", and things are probably very uneven across the board. Same is true for Google. So, when it comes to trust... It's obviously a very complicated subject. Different divisions in different organizations will have very different ability to generate trust. In my own experience, and when it comes to things that mattered to me throughout my career, I developed a strong distaste for anything branded with Microsoft's name just based on technical merits alone. Everything Microsoft was making for developers was designed to impress the rich people in the management who probably don't as much as own a computer. Since forever and to this day, Microsoft's products seem like idiotic ideas implemented by legions of slaves, who don't care about the outcome, but the complicated system of equally unmotivated slave drivers ensures the minimum acceptable quality. Google, on the other hand, gives out a very different vibe: there are a lot of motivated and competent people working for the company, and on an odd day once every few years they get to make a decent product. And then they move on and the product dies. Based on this completely personal and based on no thorough research feeling, I'd trust the first to make the worst but functional programs and the second to make programs of very uneven quality -- more of a gamble, but with much higher payoffs, if you win.
