That doesnt delete your data. Now they have right to keep it forever for their “legitimate” reasons to protect them from a user who break their ToS. All you accomplish is give up the little rights you have.
Corporations could actually do this anyway because there are so many vague rules in ToS and they can bend them however they want and without any user knowing you could all be flagged as a malicious users just so they have “legitimate” reason to do lots of nasty things with your data such as sharing them with networks who work together to prevent “malicious” users and “russian troll farms” etc. The whole system is rigged and just an illusion of protections for consumers/people.
