> So Twitter deciding to use privacy as an argument to enable a few reported on whales to beautify their record (because let's be fair, who embedded a tweet from Jane Doe?) seems at least questionable.

It's not just a few whales. Imagine you're being arrested, someone films that arrest while the cops are speaking your PII (name, address) into their radios, and the video of the arrest ends up on Twitter.

Under "right to be forgotten", you could (and can) demand removal of that video - but your data would still be floating around the net.
