Except that if a user fills in a Grindr profile, they believe they are only sharing information with Grindr/its users. The truth is that they share all of the information (in less than secure ways) with a variety of third parties and fail to disclose that fact. That's illegal in many countries (including mine) and it demonstrates an unbelievable lack of regard for user privacy or safety.

There's a very strong chance that this is illegal in many states in the US as well (not sure about federal law).

Not only does it get shared, it gets shared in bulk. That's a huge difference between the intended use and what actually happens.
