Obnoxiously broad and perpetual license over inputs and outputs.

Yes, Z.ai demands an unconditional, irrevocable, transferable, sublicensable, perpetual, worldwide license to use, modify, reproduce, adapt, publish, perform, distribute, and create derivative works from your prompts and outputs. The same license extends to your username and profile picture.

Vague prohibitions on whatever may harm Z.ai’s "interests" or even the "national interests" of any country. Prohibitions on "disturbing" or "inappropriate" content, whatever that is. Professional use prohibitions.

Discussing Z.ai is prohibited to the point even my posting this comment is against their terms of service.

And they can of course ban you if you, in the "sole and absolute opinion" of Z.ai, have violated these broad terms, and if you paid for the discounted yearly plan you won't ever see that money ever again.

Even the US companies aren't this bad.
