It’s by design I think to prevent scraping and adblocking, neither of which you can do (easily) in the Instagram app. Since it started on mobile, it’s not like they cut off a bunch of users like they would if they did the same thing to Facebook. (And, presumptively, they provide access to a fancy Instagram for Business for a few bucks that allows you to post from desktop, but I don’t know about that one. I know Facebook’s API is limited to businesses acting on their own pages for the most part these days, because at one point I was looking into getting my Instagram feed into a better interface and realized it wasn’t possible.)
