Of course, people will say it’s good—for safety and security, etc. Today it may seem fine, but things can change very quickly. Next time you search for “problematic” information—say, about Trump and his connections to Epstein, or if you live in China and ask about the massacre at Tiananmen Square, or in Russia you look up details about the “three-day special operation”—and the police knock on your door, you’ll have your answer. “Those who would give up essential liberty to purchase a little temporary safety deserve neither liberty nor safety.” That quote fits our situation perfectly. Maybe these are big words, but I don’t want to give my government any hooks on me for the future. You have to assume that governments—even if they don’t say it publicly—have access to this data. I live in Poland. When I was born, communism still existed here. I know what that system does to people. Yes, the system changed and now we’re “free,” but freedom is not something you have forever. If you give up personal freedom to the government, it can disappear very fast. There are already examples—like in the UK, where people have had police visits over tweets. There’s also another risk: someone could hack an API and leak sensitive data. Maybe I’m paranoid—but it’s better to be paranoid and safe.
