It sounds like one of those overbearing (or simply not-knowing) parent rules that'll be loosened with time.
"What? They have COMPUTERS on their bikes?! There's no way that they should be allowed to look at them while on the bike!"
Others probably agreed to the rule simply to not be disagreeable as they had (and still have) bigger fish to fry as far as getting the track program up and running.
My guess is that soon it'll be a rule that is on the books that nobody enforces. Then it'll simply be removed as a rule when things settle down.
