Google could change that. It could encrypt your e-mail so only you could decrypt and read it. It could provide for secure voice and video so no one outside the conversations could eavesdrop.

It doesn’t. And neither does Microsoft, Facebook, Yahoo, Apple, or any of the others.

Why not? They don’t partly because they want to keep the ability to eavesdrop on your conversations. Surveillance is still the business model of the Internet, and every one of those companies wants access to your communications and your metadata. Your private thoughts and conversations are the product they sell to their customers. We also have learned that they read your e-mail for their own internal investigations.

But even if this were not true, even if—for example—Google were willing to forgo data mining your e-mail and video conversations in exchange for the marketing advantage it would give it over Microsoft, it still won't offer you real security. It can't.

The biggest Internet companies don’t offer real security because the U.S. government won't permit it.

This isn't paranoia. We know that the U.S. government ordered the secure e-mail provider Lavabit to turn over its master keys and compromise every one of its users. We know that the U.S. government convinced Microsoft—either through bribery, coercion, threat, or legal compulsion—to make changes in how Skype operates, to make eavesdropping easier.

We don't know what sort of pressure the U.S. government has put on Google and the others. We don't know what secret agreements those companies have reached with the NSA. We do know the NSA's BULLRUN program to subvert Internet cryptography was successful against many common protocols. Did the NSA demand Google's keys, as it did with Lavabit? Did its Tailored Access Operations group break into to Google's servers and steal the keys?

We just don't know.

The best we have are caveat-laden pseudo-assurances. At SXSW earlier this month, CEO Eric Schmidt tried to reassure the audience by saying that he was "pretty sure that information within Google is now safe from any government's prying eyes." A more accurate statement might be, "Your data is safe from governments, except for the ways we don't know about and the ways we cannot tell you about. And, of course, we still have complete access to it all, and can sell it at will to whomever we want." That’s a lousy marketing pitch, but as long as the NSA is allowed to operate using secret court orders based on secret interpretations of secret law, it'll never be any different.

Google, Facebook, Microsoft, and the others are already on the record as supporting these legislative changes. It would be better if they openly acknowledged their users’ insecurity and increased their pressure on the government to change, rather than trying to fool their users and customers.
