I have heard someone said the runtime wasn't covered by the agreement it was just technically free.

However Unity also said the terms came into effect as part of license renewal. Requiring a new fee structure as part of a renewal is bog standard.

The main thing people were pushing back on was it was promised that old titles could preserve the existing terms.

If anyone cut ties with Unity and Unity went after them anyway would have been what you mention.
