That's not censorship. It's their YouTube video, they can allow whatever they want on it.
Some other points:
1. Why is this news anyway? They never reversed their "cannot recommend" status for the iP4 when Apple instated the free case program, calling it "a good first step."
2. The attenuation issue is real, and Apple's handling of it is crap. That said, I love my iP4, despite it's somewhat annoying quirks. (like the proximity sensor still acting up even with 4.1 installed) The free bumper I got from Apple seemed to take care of the signal problems in my home, where I get awful reception (not Apple's fault)
3. CR has long been an Apple cheerleader, check any of their laptop/desktop ratings for the past twenty or so years. It seems whenever CR calls it like they see it, someone gets upset and accuses them of bias. I mean, lately they've got fans of the domestic and foreign automakers both accusing them of being bought and paid for by the other. They're a non-profit, and they seem fairly objective.
1. They didn't reverse the "cannot recommend status". They said that offering free cases wasn't good enough unless they guaranteed free cases forever.
2. I agree Apple's handling of it isn't that great. However it is not a real problem. You can reproduce it, but it doesn't cause dropped calls unless you are in an extreme circumstance where the iPhone 3GS wouldn't have had reception anyway. Looking purely at the DB drop is like only looking at megapixels when evaluating a digital camera. They are still giving you a free case if you have an actual problem. This is only going to help people who are just barely able to get an iPhone due to AT&T coverage issues. The prior iPhone probably would not have worked for these people at all. Now that Apple fixed the algorithm for the number of bars, these people are accurately shown with a single bar. Try to drop a call with more then one bar. It isn't going to work.
3. CR has never been an Apple cheerleader. At best they are objective sometimes.
4. It is censorship. It just isn't "government" censorship. There is a difference between not allowing any one to post in a free press and not allowing anyone to post a an opposing mainstream comment in a blog. Yet they allow comments with profanity (lots of F*ing posts), obvious trolling, misinformation, and lots of posts (obviously by non-iphone users) complaining about how expensive the Apple case is. CR is doing a disservice to their readers. Hopefully they pay for it.
