I foresee a day when deepfake will be so easy and widespread that people (authorities) will acquire the habit of digitally signing what they say.
Anyone can then claim fake news about anything that wasnt enumerated on their resume.
The digital age is scarey in that it tends to preserve the past in a way that allows a mistake from five years ago seem like it happened just today.
For example, Mel Gibson. Two damaging recordings got leaked of him a decade or more ago and those cringe moments of his life will be preserved forever.
It wasn't like that before and this is not a cool feature of the modern age.
Mel Gibson is right-wing antisemite involved in a dubious cult. It's hardly surprising a concrete record of this appeared at one point[1].
You're not selling the idea that the "right to be forgotten" is for people who made just one slip-up. But there are certainly ways the right to be forgotten is reasonable - not for stars but for average people. My only point was it probably shouldn't be unlimited. That seems to strike a nerve but apparently among defenders of those who want long records of bad behavior concealed.

We've been at the point where a determined amateur could learn the skills to handcraft a false statement from a political figure.
The content is not the issue, the trust of that content is.
(In theory) the more authoritative the source, the more they'll require to treat a statement as real.
Right now you could get a good impersonator to say something stupid and send it to one of those half-trying tabloids and they'd run it even if they knew it was fake...
On the other hand a place like the NY Times might require more meat to the story, how did you get it, what was the chain of custody, etc.
Cryptographic signatures offer gold-standard, definitive proof of authenticity/non-repudiation. “Trust of content”, as you put it, is the problem they solve.
