If we met and interacted regularly, I suppose I could learn to trust you. Let's assume we get along and you are a nice person, which is likely true. However what you are asking of us only scratches the surface.
You are asking if we trust you, and the handful of co-workers you have interacted with. Even if we accept this premise, you have to see it as part of an enormously larger picture. Do I trust that you have carefully evaluated the personal integrity of all Google employees with access to user data? Do I trust that you regularly screen all new employees? Of course not, these are preposterous assumptions. But in order to do as you ask, these would have to be true. It's too big an ask.
To replace what Google used to provide, I moved to FastMail for email and mostly self-host the rest. Open Street Maps are excellent where I live, and Duck Duck Go is now "good enough". It's been a good learning opportunity for me and I'm very pleased with the results and with how much more proficient I have become with a variety of new tools. I will never switch back.
I don't hold any resentment towards Google or its employees but I do wonder how they feel about what they do. Do they see it as some noble cause, and not an effort to manipulate users with relevant ads? That's not a very charitable description of what happens at Google, but it does accurately describe how many of us see it.
