Is it? Before all this tech only specific targeted effort would store information about me. Now everyone is tracked by multiple entities all the time. It's not about undoing participation in information sharing. GPDR does not require Wikipedia to delete everything I've contributed, but the fact that I have contributed is subject to be deleted if I request so. Furthermore, there must be explicit opt-in, and that is a good thing. It's a trivial problem to purge from the backup, really. It's not a hard problem to solve. Many companies have done so before, and now we might even see standard tools to do so.
