No idea what others think, I find it a pain when anything doesn't remember my preferences, perhaps when browsing generally, but re-visiting my usual sites, I'd not expect to get prompted every time.
Rather than blindly switching off, it would be much better if it could remember the preference. I'm guessing it holds the preference in a session rather than permanently per user?
I don't use the tablet much, but do occasionally take a look in the evening when in the lounge, so it's an occasional pain rather than a show stopper.
