Anthropic secretly installs spyware when you install Claude Desktop — That Privacy Guy!

I was working on a personal project, debugging a Native Messaging helper I had written for it. In the process I needed to check what Brave Browser had registered on my laptop. What I found was a file I had never put there. It was not mine. I had not installed it. I had not authorised it. I had not even been told about it.
It was from Anthropic.
