I can’t imagine it’s not true. And you betcha “someone(s)” can . . . the same kind of someone(s) who hacked the Wayback Machine.
The internet was the biggest bait-and-switch in history. Remember how it was going to free us all? Even today, many still assume the public internet is going to keep allowing us to discuss and research what’s happening in the world on into the future, ad infinitum. Witness the libertarian dreams of Nick Gillespie, as cited in the article:
[W]hat the internet does (especially platforms like Facebook and Twitter) is enable more of us to directly enter the discussion—the argument over who is right and who is wrong. That’s a great and liberating development.
Or Balaji Srinivasan’s idea that the “network state” is, by some miracle, going to be allowed to replace the tyrannical nation-state and its various combinations (https://thenetworkstate.com/).
Of course, the scrubbing isn’t new. See, for example the forum post: Truthstream Media: Where Did the Rest of the Internet Go?
My advice to everyone: If you see something online you think you might ever want to refer back to, download it (if possible), take a screenshot, or print the webpage as a PDF. Then save a backup copy that’s not on your computer and/or print it out if it’s text.
