The problem with coupling content too tightly to a particular place is that it places too heavy a burden on that place to support all the different types of users that might want to interact with the content. For instance, I like to hang out in math twitter. I wish I was taking classes from these professors, but instead I just think about their tweets and ask myself: "that's a neat claim, could I prove it?" Twitter isn't the place for getting feedback on proofs, and I don't really want to hijack the thread with an external link, so I just do it on paper and throw it away. But what would be cooler is if I could create a link between my proof and the conversation that inspired it. Maybe some other aspiring student will notice it and start a dialog with me where we can learn from each other. Sure, I could post a link to overleaf or some other place that supports LaTeX collaboration but now anybody who wants to collaborate must go create an identity on that platform, and now we have the same problem all over again if somebody else, for instance, wants to play around with it via proof assistant software. You get this proliferation of third parties who have to manage a permissions mess re: who can read/append/edit what and how to render it to users with different preferences--to say nothing of alterior motives on the part of the platform.
