There are benign use-cases for this technology, though. For example, any TV/Radio ads containing the phrases "Hey Siri", "OK Google", or "Alexa" definitely should contain an audio beacon so that your iPhone/Android/Amazon Echo knows that a TV or Radio ad is playing, and not a human legitimately asking for a command.

…cue someone playing that inaudible signal continuously to block all people nearby using their Siri or what have you.

That's a really bad way to solve that problem, it relies on other systems following a protocol that they have no reason to even know exists.

A much better way to solve it, which is already being done (to some degree of success) is to calibrate the phrase detection to the owner's unique voice.
