do you ever save things you see on the internet that have some "scandal" merit, say for example you don't like Donald Trump and you come across a variety of material that's embarrassing to him. Or your school bully, or your gf's ex, or Macron in France, Trudeau in Canada, etc. Would you feel that other people should get to tell you to delete it because you're not allowed to use any aids to help you remember or prove why they are bad people (in your estimation)? Freedom to remember is part and parcel of free speech.
