I've used Jekyll on Github pages for quite a bit and it suited me perfectly. Being able to write a post in markdown and `git push` to deploy is all the simplicity I need.
There were so many roadblocks, that I took on having a ton of fun - but nowadays I would love to just have an easy way to write text, without thinking on design, formatting, code embedding and so on...
Sometimes I am scarred by myself when I find myself wishing I still had WP installed. shiver

Also this way he might have some additional exposure of his novel by people stumbling upon him while on medium.
IANANE (I Am Not A Network Engineer) but I imagine with open firmware like Coreboot and networking distros like Cumulus and pfSense (BSD) and the whole Open Compute Project it might be possible to run a completely open-source hosting company. Well, no. Your UPS's and other auxiliary hardware are probably running closed OSes. Darn.
I'm not aware of any efforts to write open source drivers for any high speed ethernet chips, though I haven't looked much. Intel's (formerly Fulcrum) switch chips have open data sheets (but not the reference code, simulators, etc) so it would at least be plausible to start there.
I used Medium for a short while, for these reasons, before realizing that it's actually pretty bad. There are a few heavy hitters on the site and everyone else is busy pandering to one another with fake internet outrage and "listicle" style articles.
That said, there has been some interesting journalism being done there. And it's interesting seeing the White House and Obama using it as a public platform to issue addresses and policy commentary.
I think for most people it really just comes down to a mix of Medium's beautiful design, a strong existing community there, and laziness. You'd be surprised how many times I've been told by friend's to cross-post my stuff to Medium for exposure, but so far I've done my best to hold off.

Medium's business model is: you just started your own website and don't have enough content there to rank well with search engines/attract visitors? No problem! We got a shitton of content and are well indexed. Just write an article for us (add to the pile!) and we allow you to link back to your own project.
Medium pretty much is on my ignore list. The only thing you find there are fluff pieces without substance that are meant to drive traffic elsewhere.
And there really is not a lot of substance to telling the world that you can use Markdown to format a book (though I really wonder he didn't use LaTeX).
