There are different narratives. What I believe I heard on BBC radio was that the sender intended to just send a few records to the recipient but accidentally sent the full dataset of 18,000 (or 19,000) records.
Other sources, like the one I linked, say the error was that the wrong recipient was emailed.
It’s surprising that as big as the story is, reporting of the tech details is lousy. A couple sources say the data was a spreadsheet, which seems to support what the Guardian says.
Perhaps.
One thing I find irritating with git is how it handles blobs. The doc has lot of small graphical images which do not need version control, but they need to exist along side the controlled objects. I will have to put them under version control just to get them in the same area.
I might still try latex2rtf, if the collaborator terns out to be quite low tech. But I guess I should have low expectations of a 2 column doc coming out well.
