This reminds me of RMS and GPLv3. Now I personally don't use GPLv3, but this here is literally a case-in-point, and it is not even only limited to the "cloud-only". Because this now includes a company threatening to sue a developer. If they sue one developer, they, by proxy, sue all of them in principle. So RMS was kind of right.

How does the TOS get involved here? I don't use their TOS. Why would or should they be able to enforce it? Note that it also depends on the jurisdiction. For instance, Microsoft's EULA never had any legal bearings in the EU.
