"Human rights" are a nice idea, but unfortunately, they're a joke in practice. History clearly shows how quickly even the most basic rights vanish. If you aren't liberated, if you don't have the power to defend them (whether collective or individual power), rights are only privileges. So in that sense, I can't consider it a human right.
But do I think someone should be free to pursue that goal? I'm not sure. Remembering history is really important in our development and learning. For a more extreme example, if someone, say, worked as a hitman for organized crime, killing many people, and later regretted their decision and requested people forget about them, I don't think someone who has had such a profound impact on a society should be able to simply demand that anyone, let alone the whole of their society, ignore their past actions.
I believe people can appeal for forgiveness, or even ask people to forget them, but I don't believe in a universal right to be forgotten, such as legally punishing people who discuss someone who wanted to be forgotten (I really don't know how else such a right could be enforced).
With all that said, the GDPR "right to be forgotten" is a distinct and wonderful thing and I hope more countries enforce it. But again, know it's only a privilege. A company can literally just make an illegal copy and pass it around like candy, if they believe they can avoid prosecution.
