Actually wifi does work that way, notwithstanding the odd word 'crash'. It's entirely possible that so much bandwidth is being used by the Google network that his network has extremely high packet loss and is effectively useless, especially if Google is using better gear (like directional antennas). And you're aware there's only actually three channels, and each bus wouldn't be using the same one, right?

But sure, use a partial understanding of technology to generate a narrative in which this guy has only a self-created problem, and take from him the benefit of the doubt. Then we can turn off our empathy circuits, reject this very dear example, and continue pretending that its workers (and users) are not pawns of a malevolent Google.
