Incidentally pi stopped working today - under the Claude subscription ban for other harnesses. Awaiting a plugin that fixes it.
How is anthropic enforcing the ban, are there identifiers sent from harnesses?
easy to circumvent
but would fall under "circumventing security protections"/"hacking their API"/etc. And due to the sometimes very unreasonable laws the US has in that area they can use that to go after anyone providing a workaround.
Through that maybe won't work well for the EU, I'm not sure how much the laws have been undermined in recent years but we had laws which made it explicitly legal to circumvent DRM iff it's for the sake of producing compatibility (with some caveats).
