Based on a web search, https://bogdanz.me/work/diddu.html might be a working mirror of the proof of concept.

It appears to contain a 10MB long UTF-8 mess in both the og:title meta content and in a mailto: link.

I'd guess it's supposed to crash iOS apps by either posting that link if it displays links in a thumbnail element using og:title or otherwise by pasting the huge mailto link contained in the webpage, or perhaps only the e-mail address.

Could someone just use some sort of fuzzing software to generate these?

Just keep trying many until one hits.

You can, but the number of possible inputs is huge and fuzzing won't prove that no such input exists.
