My privacy stance has evolved to just assume everything I do online is public.

Even if we fight and succeed in stopping a tracking mechanism (third-party cookies) we discover that another one is developed (fingerprinting). It's times when you think you have privacy/no one is watching that you're most susceptible to doing something you might regret.

If you consciously acknowledge that your digital life is public, you can consider performing activities using other mediums. Calling instead of messaging. Shopping at stores with cash. Journaling in a paper notebook.
