Unfortunately, those recordings would not be out of reach because while you cannot be compelled to testify against yourself, you can be compelled to testify against someone else if the prosecution has reason to believe you have testimony material to the charges. And that is why this sort of thing falls down.

People who breach privacy do stuff with that information. Governments who breach privacy do very little with that information, and mostly not to me.

That's not to say it is acceptable for governments to do it - they must not. But if find it weird to read on HN peoe saying that it is terrible for a government to breach privacy but then admitting they do it to their users.
