There is no precedent for AGPL enforcement against Chinese companies, so no, not really.

Feel free to post a docket if you disagree though. Also there are plenty of cases for ToS violations look up Facebook vs BrandTotal, or more recently Epic vs Apple.

In the same way no one here cares about archive.org paywall circumvention, non techie end users don't care about open source violations (why should they). Look at the very link we are discussing for proof.
