I had a quick look in the chronology, and the first two articles I checked at least touched the topic:
(As well as several other topics people regularly have questions about)
Despite the fact that, especially in the first months after the campaign “we, the people” complained lack of information, over the years quite a lot of knowledge has piled up (of which @amosbatto’s FAQ does an excellent job of summarizing).
So, one problem might now be finding all the info we have.
But the other is probably a variant of what @dcz described in her latest article I love you for your personality:
Just because you learn something doesn’t mean you understand the implications and appreciate them.
“L5 has now mainline support !!!”
“so ..?”
“lifetime of updates !!!”
“and that’s exciting …?”
“plus a plethora of distros to choose from !!!”
“a what?”
“plethora is greek and…”
“no… that other thing. Distro …?”
“uh… somebody takes the source code and compiles …”
“source code? Compile?”
…
But I guess your right, there’s certainly value in trying to communicate such things. Just wondering how much impact blog posts have outside the Purism bubble of converts 
Well made videos might work, but it must be entertaining if you want to teach such implications. Maybe humor could work. The above conversation was slightly inspired by a YouTube outro of a German satire show, where somebody tries to explain video subscription and mouse clicks to… Isaac Newton.
