GDPR requires a full disclosure of which data and users are affected and when it happened, which I think is fair for the average user.
Private bridges, have owners who give an accounting to no one when they collapse. At best, if you have standing you can sue them and they will defend themselves by giving an accounting for why it’s not their fault or they did their best.
GDPR is a good idea but there must be supervision for it being applied as defined.
