Re: I used to concider Yahoo! as the scourge of the email giants..
Make note that of all these corporations and the hundreds if not thousands of people who knew what was going on, NOT ONE went to a newspaper and became a confidential source. This took place over years and no one said anything until Ed Snowden snatched the honor.
If they (Google, Yahoo, MS, et al.) truly felt this was unconstitutional they should have A) Made a public declaration and fought it out in court or B) made a bee line for the newspapers as confidential informants and stopped this in the tracks.
They didn't and here we are. The one person who did something about this is vilified and on the run from American "Justice". There's only one hero in this story.
