Rarely, I mean rarely you get good ads from Microsoft. Most of the time, you get notorious advert, like this one which makes you wonder whether at times Microsoft’s PR resort to ‘any news (even bad one) is good news’
However, I really like GMail Man ad.
It’s a good education piece. It serves good purpose of reminding everyone that your email can be read easily by everyone, including Google. That’s the price you pay for using email, everyone in the chain, including Microsoft, can read your mail if they choose to.
My point-of-view is at least Google is clear that they have machines that can and will read your email.
If Microsoft sees not reading emails as one of their important selling point, then they are correct. As always I do believe that the only way to reduce your exposure to snooping is to run your own email server. Your email can still be read in transit, but most of the damage at present is done by snooping stored emails on server, or your destination email server.
