Claude Code fails to fetch or create the GPL v3.0 license when asked

Is it just me? What in the GPL v3.0 license causes CC to run into this issue?
Note that, if I copy the entire license into the prompt, it can successfully create it.

Now let me add the GPL v3.0 LICENSE file:
Fetch(https://www.gnu.org/licenses/gpl-3.0.txt) ⎿ Error: Request failed with status code 429
Let me create the GPL v3.0 LICENSE file directly: ⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_er ror","message":"Output blocked by content filtering policy"},"request_id":null}
It's best to explicitly to disallow things like that in CLAUDE.md
I would not be surprised if there are some guardrails in place specifically to keep licenses from being generated. If a client accidentally re-licensed their entire source-available product because they weren't paying attention to what Claude Code was spitting out, I imagine they'd be pretty upset (I don't know if such an accidental license would hold up in court, but nevertheless).
