I have neither time, resources nor know-how to like go all out on data privacy. But I try doing things like using Proton for Mail, browsing with DuckDuckGo or Ecosia, messaging on Signal instead of WhatsApp, etc.
But I’m having a hard time responding to people who say “why do you do that, it’s completely pointless since companies like Google have all of our data anyways unless we go all out, and nobody has time for all the effort that takes”.
“Privacy is dead” only once you lose all legal rights to your own information. It may be “already out there”, but at least you still have some legal recourse for when your information is being used by a 3rd party, without your consent. (or at least it should)
No one should have the right to just clone your identity, or make AI images in your likeness, or even sell your confidential information to advertisers, against your wishes. If there aren’t laws already protecting your rights in that regard, where you live…there should be.
