What's the real scope of hardware openness?

I'm definitely willing to believe that there are tech problems, the GPS
protocol into the chips we are using, closed firmware and all the rest.

And I admit I really know nothing about mobile comm problems.

Anyway, there seems to be some FUD here to me.
But then I am probably wrong. Could you confirm these

Isn't that the same that having many users sharing the aerial
bandwidth when communicating with the same big GSM antenna?

Couldn't this problem be worked out? Some powerful (wired?) connection
between the 'islands'. I mean, if you are talking about big group of
users, say a town or a big building.

Emule does a great job in avoiding the abusers.

Again, the protocol should take care of who gets what part of the bandwidth.

Maybe mine is a naive idea, but I don't agree. If the protocol is well designed.
