Allocator, you seem to miss the point, either deliberately or otherwise - most of your posts infer a vested interest in the product, come what may. That's your prerogative.
However, if you issue a product with a manufacturers warning that a feature of its use may be forbidden in certain countries, common morality (and sense) SHOULD dictate that, if that feature is provided as an option, it should be disabled by default if the alternative is liable to impugn the integrity of the user, and render him (or her) liable to possible prosecution in those countries.
Otherwise, some unsuspecting user could well be involved in a legal process, and his protests that he "didn't know" would not serve as a defence.
I think if I were in that position, I'd sue the manufacturer for negligence.
If Airnav are as altruistic as they make out by delaying network traffic for five minutes for a similar reason, then there is no real excuse for not making sharing an option which is defaulted to "off". Unless of course it is not in their interests commercially.
Besides, if as you say, it's not a problem for most users, then surely it is just as simple for the option to be "off" to start with, with the user option of turning it on.
What all this has to do with providing you with yet another opportunity to knock the competition, heaven only knows.
