Thank you for taking the fight and making a scene! I tell myself that I will send Facebook my GDPR letter one day, but just thinking about the time and brainpower I’d have to spend to understand exactly what my rights are and how to exercise them, makes me dread it.
Facebook responds with an overload of legal nonsense to discourage people from replying. I overload them with a lot of non-legal nonsense. In the end I just want my data—it's my legal right.
