I think that's a bit cynical. This is the President of the USA we're talking about. His words matter for the sake of history. I believe it was smart to capture a log of his statements. It will be essential to the record. They should have also disallowed him from deleting tweets, but I suspect they have a copy of everything he ever posted since they claimed it was significant discourse.

The responsibility of archiving presidential records should really not fall on a private company. If I had to put money on whether Twitter will be around a couple of decades from now, it'll be an easy "no".

I believe the Library of Congress archives all historically relevant tweets. Up until 2017-ish they archived every single one.

I'd be very surprised if all Trump's tweets weren't scraped and saved in official archives.

Pretty sure you can buy Mein Kampf at most US bookstores. I know I bought a copy in high school, though I never did get around to reading it.

But it would be a trove of data if we did.

We don't know the Minoan language, and we get by. But that doesn't mean we don't value knowing Greek.
