Every mobile OS requires the application to request to use your location data and be approved by the user. Moreover, most applications are not constantly collecting your location data, and even less frequently storing it permanently on a separate system. "Sending your location to every app you installed" is quite the overstatement.

Well, considering good sarcasm has so much to do with inflection, tone of voice, facial expressions, etc, it is not always so obvious in plain text on a comment thread when someone is being sarcastic. I've experienced this myself in response to my own facetious comments enough that I've realized that expressing sarcasm in writing that is generally understood to be tongue-in-cheek by all who read it is not necessarily an easy thing to do.
