I would have thought this would be more of a story, I'm surprised there are so few comments.

"Claude Desktop, an Anthropic application, reached across the trust boundary between two independent vendors, and wrote configuration into Brave's application directory. The principle that an application does not silently modify another application is so obvious it rarely gets stated. Anthropic broke it in silence."

This is the key point for me - ask me, let me remove when done. That would be all it takes to not abuse trust.

It's being suppressed by the mods. I'd bet my house on it.
