I agree that for you it's 3 more clicks, but for the millions of other regular users, it's less useless info on the way.

People have to get that it's a product for many, not for all. You can agree with hiding emails or not, but a company as large as Google wouldn't hide it just for the sake of it. Obviously there was research and data that backed that change.

Bottom line is, if it was your company, you'd hide stuff to improve the experience of 90% of your customers at the cost of a few without another thought.
