I thought some about this, and I am a bit afraid about "feudal lords" of some other kind:
I'm starting to self-host my content and services as I am starting to have some income (beginning of my career). However, I have to pay for a domain name, internet access, etc. I can afford to pay all of this right now, but I have no guarantees that the content will remain available in the future. The biggest unknown for me is the domain name, as it sounds much like a single point of failure: what if my registrar closes, or refuses to do business with me, or if I can't afford it anymore? Medium provides some relief against this, but not enough that I would care to use it.
How could this be "solved"?
Ideally, I could write a static page, sign it with a private key (maybe associated to a human-compatible string), and then host it in multiple places. A search engine could pick the right mirror, and interested people could choose to mirror the content.
This sounds a bit similar to IPFS, but with the possibility of picking your hosting place and the content you mirror.
And to write something more about paid apps vs. add-based ones (which cropped up later in the discussion thread), when I was younder (kid/student), I was unfortunately in no position to buy paid apps (no income), nor to self host myself (I tried multiple times, but it was a pain to host even static content at the time). It seems to be getting better (github education pack, github/lab pages, etc), but I think that we as a society should think more about what is made available to kids. A free dynamic DNS and hosting service should probably be a minimal offer if you want to make them interested in tech. It could be also a good plan (though long-term) for a hosting platform to gain their trust/mindshare. Also making nice apps freely available to them.
Unfortunately, I had no e-mail address provided by my high school at the time or earlier, so I wouldn't have been able to get a github student pack (if it existed). I think that's something that should be solved at he state level.
