Does Your Company Censor the Content for You?

JAZ asks: "A few days ago a friend of mine and I were discussing this story. He was trying to make a joke about some content in the article that might be considered 'inappropriate' (the bit concerning 22,000 files). I didn't get his joke because the interesting bits weren't there. With a little investigation, I determined that my company's proxy server was delivering a modified version. Is this a common practice? Has anyone else noticed something similar?"

"In this case, words were not just filtered out, but the text had been changed so that the document still made sense. I suspect that someone monitoring a log and suddenly saw a document show up a bunch of times with the offending text in it. Then they modified the cached copy (I was viewing it a day after it hit the Slashdot front page) to make the alarm go away.

I have mix feelings about this, on one hand, even though the text in this case was meant as a joke and the content wasn't very offensive, I was using company equipment. But on the other hand, this company is a government regulated entity which isn't above pressuring its employees to vote the way management thinks is best (whether it is or not is a question for history). So I guess I'm scared that the company could push an agenda though 'stealth channels'. I realize that the information I read online can't always be trusted, but there are many people who don't know that. It's probably important to note that, while there is a policy of acceptable computer use, there has never been a notice that they might change the content we see online.

What are the feelings and/or experience of the Slashdot crowd on this?"
