When I wrote this in my book, I wasn’t thinking of any specific person—just a process and phenomenon. And yet, here we are. The rise of trolling as a political strategy, the weaponization of disinformation, and the erosion of state integrity… all unfolding before our eyes. ⚠️

This was such a great conversation with @cyallianceprez.bsky.social and @intel.bsky.social - check it out. Information sharing has evolved - time for our policy to evolve, too.

Honestly, me right now. Pretty much exactly what I woke up thinking this morning.
"I've had a few days to calm down and process things, and I've come to the realization that I was wrong to have had faith in humanity."

Seeing how Bluesky is finally taking off, allow me to introduce myself: I cover cybersecurity for Ars Technica, with a focus on new vulnerabilities, exploits, technical research, and telemetry that hasn't been published yet. I post mostly about breaking security news, privacy, and climate disaster.
