I agree, and it's nuts.

This feels like less of an issue with anthropic per say as it is a broad reading/misuse of the law's original intent.

You're absolutely right, at least according to my own quick check on Gemini. I find this state of affairs amazing.

In my country, no "overt act" is required, but both here and in the US a "conspiracy to commit" charge requires an agreement with a second party. This is indeed consistent with a very broad interpretation of "no thought crimes".
