I understand why people fall for it. It's called private browsing.
Privacy used to mean seclusion from the knowledge and observation of others.
Now it means only you and a slew of corporations and government agencies from all over the planet, can know what you're doing and the data is stored in a massive database for eternity.
Seclusion from the knowledge and observation of others is still a worthwhile endeavor and I sorely miss it. It is very difficult to nurture your own mind when your body is constantly "on the record".
