And why does the real source remain obscure?

You can blame the chicken/egg problem, but ultimately the reason why decentralized systems don't overtake centralized systems is that they don't offer much of an advantage over them, so nobody cares enough to learn how to access them.

I mean, suppose Cloudflare/whatever goes down and the site is inaccessible: would you:

A) Grab the link, and go figure out how to pull it out of IPFS directly

B) Grab the link, and paste it into archive.org

or

C) Go grab a coffee, then come back and refresh the page (because when Cloudflare does go down, it tends to be only down shortly)

B and C aren't perfect, but they're close enough. Doing A takes effort and frankly isn't worth it unless you're doing it as a hobby.
