This is advice for a world that doesn’t exist any more and hasn’t for a long time. The only thing you are going to do following this advice is to stand out immediately amongst a sea of data that you are someone who is taking very unusual security measures and worthy of a closer look. It’s a very easy to identify signature and it’s very literally the opposite of what you should be doing in 2025.
Buy a burner phone with cash without taking your main phone and stash it somewhere. Then, before protest, take phone from stash and bring it with you
