I don’t trust Big Tech and you shouldn’t, either. You’ve heard me say for years that free email services like Gmail or Yahoo aren’t really free. There’s a big price to pay — your privacy. These free email sites scan, analyze and save details of every email you send and receive, giving Big Tech a very intimate and detailed profile of you so they can easily sell your data to the highest bidder.
