One of the regrets I still remember, even after many years, involved a client for whom I also managed their email. It was just 10 mailboxes on their VPS, which also handled other tasks, with no additional costs for them. There were no storage issues, and they were extremely satisfied.
One morning, the owner told me they would be migrating "to Google". I was stunned and asked for the reasons, convinced something was wrong. He explained that he was doing it because, in his opinion, all "serious" companies were moving to Google, and they didn't want to be left behind. I explained the concept of **privacy**, and they paused their plans.
After a month, he came back at me. He had reconsidered that, likely in light of what I had explained about Google, *I* could potentially read their mail, and therefore he wanted a more private solution. I confirmed that yes, in their current setup, I could access their mailboxes (simple maildirs), but ultimately, what interest would I have in doing so? And then: was it better for Google to analyze every single email (at the time, there were no indications they weren't doing this) or for me to potentially see them (something I would never do due to ethics and privacy)?
His response: "Well, you know, Google has so many clients that they wouldn't be interested in our mail, I imagine."
I was so disheartened that I said nothing else: if you trust Google more than me, I've failed (as a consultant) and you don't know me (as a human being).
