Yes Apple will terminate a dev account for not respecting the terms but I am not aware of Apple or Google trying to bring to justice developers that sold private data, at least in US there is a big resistance against having a GDPR like law so you could use the courts to punish some developers. Also we know that Apple (like Amazon and others) used contractors to have them listen to private recordings of users without asking consent (like hey user , I do not understand this can I send it to the cloud so strangers can listen and do stuff with it ?) , so for Apple privacy is a tool for making money, it aligns with your interest until a point (but as with Siri example you can see it is not 100% aligned with your interests)
