I agree this is appalling. This is what happens when software engineers good at one thing mistakenly assume they must be good at security.
When it comes to intra-airliner security (e.g. the cockpit door) is that an FAA mandate or TSA mandate? If the latter, then hopefully the TSA can require the passenger LAN to be disabled instead of banning laptops.
