What happened to the right to privacy?

Many are upset about a Chinese spy balloon hovering over the United States before it was shot down, and rightfully so. But what are we trying to protect? Our privacy. We don’t want foreign governments spying on us, even though we spy on them. But the fact is, we don’t really have any privacy any more. Various amendments in the Constitution seem to provide us several privacy rights, but how private is anything any more? And much of our lack of privacy is due to our own behavior. We tell the world on social media our every move, and add the pictures to prove it. If you own a cell phone, it can be learned where you are at any moment in time. You willingly download apps to your phone without reading the fine print which allows companies to access practically every bit of information on your phone, including your texts, pictures and browsing history. And it’s all for sale. Even just walking down the street requires us to forfeit our privacy, with cameras on just about every corner. It isn’t clear why that Chinese balloon was hovering over the U.S., but I can’t imagine it revealed much they didn’t already know.
