True, though with airplane mode they might be skirting the law as it now touches the whole interfering with FAA requirements are. Also it would seem it would be easy to verify for anyone who opens the case what the radio does.
That's not how subversion works. The subverted system will in fact turn off wireless in airplane mode. It's turned back on by a trigger. Stays on long enough to do the job. The commenters imply they would be using it outside an airplane. So, FAA wouldn't even notice.
