@yaelwrites good stuff, but I'm surprised about the QR suggestion; I've heard a lot about stickers covering legit codes that can collect payments or even set up credit card theft. Quishing (QR phishing) is a larger threat, mostly coming from email and social media.

I'm also surprised that ad blockers aren't suggested, as they're good defense against malvertising and surveillance overreach. This brings me to the question of who the enemy is: stopping hackers is one thing, but some of us consider corporations and governments to be invasive or even dangerous, depending on where you are. In these scenarios, ad blockers, VPNs (from trusted providers), and airplane mode (especially at protests) can be godsends.

@yaelwrites glad (but not surprised!) to see your name on the letter. what an excellent resource!
