Some say that information isn't "private" anymore and none of this matters.
The only reason it's not private anymore is because our own government is using unconstitutional, suspiciousness spying on its own citizens. It's illegal for corporations to spy on user's private emails, etc. as well. Federal wiretap law exempts interception of communication only if it's necessary in a service provider's "ordinary course of business".
Some say that mass, suspicionless surveillance is for the purposes of security.
There's no evidence that the only purpose of collecting Americans' private information en masse is for security. As a matter of fact, evidence shows that collecting all of our private communications has done little or nothing to protects us. Even our own government is now admitting this while also admitting it's overreach to boot:
NSA review panel casts doubt on bulk data collection claims
" ... The members of president Barack Obama’s surveillance review panel on Tuesday rejected some of the central contentions offered by the National Security Agency for its bulk collection of phone records, including the program’s potential usefulness in preventing the 9/11 attacks."
For all we know they collect all of our data to thwart free speech (which is already happening with journalists)
Advocacy groups say NSA threatens free speech
Don't think our government is capable of using wiretapping against us?
Look at the Watergate fiasco with Nixon. Much more recently, imagine what the corrupt people in the Chris Christie administration would do with mass surveillance.
One only has to look at human nature over the course of thousands of years to know that absolute power corrupts.

Never give any small group of people absolute power or they'll send us towards despotism.
It's already on the way here in America. I challenge those who don't believe it to go outside with some peaceful demonstrators that bring up issues like wealth and income disparity and watch how fast the tear gas hits their faces and batons crack their skulls.
Or try to organize a peaceful activist group in the United States that says anything corporations don't like and watch how quick it gets infiltrated and spied upon with the very same spying tools Snowden has exposed.
Don't believe that can happen here? It already does:
