Bill Blunden writes a long rant warning against trust in encryption and the companies who peddle it, pointing out that no matter how good your encryption algorithms are they can be subverted by the people who use or implement them.
Greenwald believes that leaked documents will induce Silicon Valley to clean up its act. But given the systemic forces at work, Silicon Valley will likely continue to consort with spies. In light of wage cartels, slave labor and wanton tax avoidance, it should be clear that high-tech companies have absolutely no shame at all. Like a textbook psychopath, most corporate entities really care about one thing only: profit. Caught in bed with the intelligence services, they'll simply keep on selling more lies.
Why should they clean up their act when it's cheaper and more profitable to sell snake oil to rubes? In the C-suites of Silicon Valley managing bad publicity is largely a matter of cleverly devised public relations. Having beguiled their users with a newly minted "encryption everywhere" sales pitch they will return to their old ways. High-tech executives, you see, want to have their cake and eat it too. People raking in billions are used to getting what they want: patronize the unwashed masses with talk of improved security and simultaneously maintain their links to their brethren in the intelligence services.
Read it all. Basically, be more paranoid.
