What are you people hiding... I call bull**** on all the "PRIVACY" you supposidly need...
No one cares that ya'll spank it to off-brand pr0n..
And when some radical decided your favorite material is illegal and starts a which hunt?
Jews were legal in Germany before WW2.
It wasn't (and still isn't) illegal to be a socialist in this country before McCarthy went on his hunt.
It still isn't illegal to be a Muslim or gay in the U.S., but you might not know it in certain places. How about if you are either and the government knows it and decides to use it against you? I hate coming off as paranoid, conspiracy theorist, but there is plenty of evidence to back this up.
The more someone knows about you, the more they can use that against you, why do you think advertisers pay big money for data. Government isn't the only one you need/want to hide your data from.
It's your information you own it. It shouldn't be given away or sold without your permission.
It is your info and only you can give it away, and you do, by storing it on their systems. It's your data, stored on Google's servers. Google doesn't have ownership, but they have control of it. This is the core of the whole ownership issue
Personally I prefer to just buy a domain and pay (hardly anything these days) for hosting.
Then you can have any features you like and get a more personal email address, when I see companies and professionals using @gmail.com it makes me cringe a little 
It's still someone else's server you store it on, therefore you are "giving" it away.
Unfortunately, running your own server actually puts you at higher risk of being hacked, since you know less about security than these companies do. Gmail and Mac mail has been hit before, and Hotmail has been hacked too many times to count
My personal server (running Linux) gets hit with a hack attempt once every 30 seconds and that's
after firewalling Africa, Asia and Russia.
The feds can always just slip a box between you and the internet and get everything anyhow.
