But do they really need to answer those questions? Clearly they don't want to publisize the establishments that they called. The most likely record calls (although they probably don't know if the final product will) and why would they confirm that they have done something illegal.
It doesn't hurt them to not answer these questions, and they definitely don't want to answer some of them, so why would they?
It could be that the audio is only edited in those first several seconds. That a normal call goes "Hello this is [business name]." Then Google starts recording as it replies that the call is being recorded. And then starts ordering.
And that's likely why, weirdly, no business identifies itself in the audio. They don't want to admit to ANY editing because it would open up MORE questions.
