To future historians—not just of computing, but of humanity—the current period will be a dark age.
How was Facebook used by students in the 2010s? We cannot show you, that version of Facebook is not hosted anywhere.
How did MySpace look around 2009? We don't really know, the Wayback Machine only shows a limited amount of static content, and there may only be a few surviving screenshots
What correspondence did Vint Cerf have as president of the ACM with other luminaries of computing industry and research? We do not know; Google will not publish his emails.
What was it like playing Angry Birds on an iPhone 3G? We do not know; Apple is no longer distributing signed receipts for that binary.
What did the British cabinet discuss when they first learned of the Coronavirus pandemic? We do not know; they chatted on a private WhatsApp group.
What books were published analysing the aftermath of the Maidan coup in Ukraine? We do not know; we do not have the keys for the Digital Editions DRM.
How was the coup covered in televised news? We do not know; the broadcasters used RealVideo and Windows Media Encoder and we cannot read those files.
We have to ask ourselves how we are going to preserve and transmit knowledge about our age to the next generations. Knowledge about an age where information is produced, consumed and discarded within hours, days or months, or where it's only stored on the server rooms of a handful of corporations, with no guarantees that those businesses will exist in the future, and with no way of accessing that information unless a certain set of regulatory, hardware, software pre-conditions are met.
That's why projects like the Internet Archive deserve more recognition and funding. That's why web scraping should not only be a civic right, but a civic duty to the next generations. Otherwise all the knowledge about the great age of information will be transmitted orally - with all the distortions that such transmission implies.
I do agree with the online services part, but

The iPhone 3G is very jailbreakable.

It's not like ffmpeg is going to poof out of existence in the foreseeable eternity.
