> In other words, if X has a public API and Nitter is using it, then neither Nitter themselves nor the Nitter users have to agree to any terms of service in order to do so.
That's not true. Publicly available source code with licenses dispute your claim.
(IANAL) That's copyright law and not contract law. Perhaps X could try to put a clause in its ToS that publishing content there grants the copyright to itself, but I'm pretty sure it won't be accepted well even if it's legal.
License != ToS
Copyright law applies to all citizens whether or not they've agreed to a contract.
What are you talking about, specifically?
Using software with specific licenses? Or making modifications to it?
That is substantially different from reading the public APIs.
