I never trust that I can delete my collected data from anyone. At the point you hit the delete button your data has likely already been spread around to backups (including offline/offsite), been aggregated with other's data, shared with "partners" and sold to other companies and data brokers. The idea that a "delete" button can somehow undo all of that and keep your data out of others hands is absurd.
