> Government snooping is a separate issue, but as far as I know there are no major email providers that a non-technical person can use that aren't vulnerable.
But at least, those other email providers are different that your web search provider - while if you use Gmail, your profile will also contain your searches (if you use Google for search), visits from those searches, and then also data from other Google services you choose to use.
If you're talking about government snooping, they most likely can aggregate information from different sources.
If you're talking about the nebulous "one company has all my information and may do something evil" argument, I still say that it doesn't matter. Email is by far the most sensitive thing most people do online, so if there was a real threat from a company having all that information, also having searches is not substantially worse.
Regardless, I still don't see a credible threat of harm from Google having this information that outweighs the actual threat of hacking.
