This isn't a ban by Qatar Airways. They are highly opposed to the ban. And on the water ban enforced at the airport (and sometimes the gate), Qatar Airways doesn't charge for beverages (including alcohol), they'll happily give you litres of bottled water for free (although for some reason odd reason they cut the label off when you ask for a 2l bottle - and no its not tank stored potable water - i get thirsty during long flights - tis just easier this way).

I think its more dangerous. How often are they yelling at people that gate check to not have any batteries in their luggage? So is it okay now? Are they putting all cargo in sealed metal containers to keep any fires from spreading?

Move along, move along...

Completely agree. Also "would you like to login to your social/email accounts while on using this public, potentially spyware, keylogger infested machine of ours?"

Presumably you can use a very small bomb more effectively if it is in your direct control. Perhaps by detonating it while holding it against the side of the plane while at cruising altitude.
