A big impact may simply have been the advent of greater storage and bandwidth capacities allowing bigger emails. Along with that, email clients threading messages for you allows for relatively seamless review of history if necessary.
And, the "selectively quote, then reply below" concept opens the door for biased selective quotations, where anyone getting in on a thread in the middle will likely be misunderstand the true context of the email they're receiving. Better to have the whole history, or none of it.

I have literally hundreds of active email conversations. If you think I can understand a reply without first refreshing my memory about the context then you're much mistaken. What you say might be fine for people with just tens of conversations, but there's no way it works for me. > Along with that, email clients threading messages for you
allows for relatively seamless review of history if necessary.At least, that's what happens when I use any of the standard email clients. but I don't. I use a really old, completely non-standard email client so I can, on every reply, extract the text that matters and assemble it into a single conversation, which I then continue.
Yes, I freely admit I'm unusual, but I find it incredibly frustrating that all the systems other people say "Well, it works for me" are, in my context, unusable. And when you say:

... you are buying into the fallacy that what works for you should work for any right-minded person. Having clients thread the messages actually compounds the problems for me.
