The first law of freedom in the 21st Century seems to read “Be careful of what personal information you put on a computer that’ll be connected to the internet, and be careful of what put on websites that can be traced back to you.
Even so: Before the internet was invented there were other ways of collecting information about you e.g. telephone monitoring, public records search,
or (for the really reclusive) a “chance introduction” with the agents. All these methods are still used, the internet is just a depth increasing,
cost reducing option for state surveillance.
In theory the internet may be 50, 50 for freedom verses totalitarianism. But if-when the state makes the right investments, in the wrong places it
could easily be 40, 60 or less.
Many politicians did not succeed in politics because of their commitment to morality, ideals of freedom, or anything much else connected to making the
world a better place! This was true in history, and it’s true now. Caution never goes amiss.
