See the Droid X ads where they slam the iPhone 4 for this problem, claiming they're immune due to a double antenna design.

Most folks wandering around the planet have no clue about RF and near-field effects, but then most folks wandering around haven't had much experience with carrying around RF devices or with gear operating at picowatt sensitivities.

But that gear is now increasingly commonplace.

Please explain to me why you believe that knowledge - regardless of its source - is bad.

Please also explain why that knowledge - again, regardless of its source - makes you a "poor sport".

RF is not magical.

OK, yes, there are some days when RF and antenna design and EMI does seem is magical, but that's not the same sort of magic. And you can learn why your receiver was getting bagged by that metal sign that was wired onto the chain-link fence actually is re-radiating spurious signal. Once you find the EMI.

Or once you realize that grabbing onto the antenna or getting into specific spots of the near-field might not be a good idea.

Again. Data. Goodness. Even the biggest idiots on the planet (and Apple is not among those folks) can get stuff right once in a while.

So. Why is data a "poor sport"?

There's no "data" provided here. There is no context, explanation, or insight into what is going, or why. If accompanying the video there was audio or discussion explaining how the person's grip of a phone impacts RF signal, then it would be less open to (mis)interpretation.

Data would be excellent. This video provides none.

The poster you responded to didn't, by my reading, say that Apple were poor sports. He said that this would be portrayed as them being poor sports. Whining is normally a form of poor-sportsmanship, and this comes across as whining (at least to some people).

'So. Why is data a "poor sport"?' Because it's not data, it's just some hand holding a phone and the bars are dropping. No explanation whatsoever.
