There are only two reasons it would need to be private:

(1) you're collecting data where if it was public, people would be outraged. That's spying.

(2) you believe the data is anonymous and valuable, but only you / your group should benefit from the insights it provides. You're afraid someone else is going to 'take your ideas' and execute them better than you can.

Point 1 is ethically wrong, in my view. Point 2 is not ethically wrong, but IMO means what you are just trying to run a monopoly on an idea. That's fine, people do it all the time, especially companies - but I think this is wrong for the progress of humanity overall and I dislike it.

Someone saving all the letters you have written them isn't spying on you, you have just been careless to write down so many private things.

The easier way is to assume all signals emitted by your computer are being consumed somewhere (Hey CIA friends!) and not emit anything you don't want detected.
