I'm put off by increasing centralization (I won't name companies, you know them) and would like to know who still does it "old school", hosting their own blog. I'm especially interested in the technology behind it.
E.g. mine is grisha.org and it's hosted on github pages and behind cloudflare which is how I get SSL. Cost: $0. The blog itself is Octopress and it's kind of aging, I might look at Hugo next if/when I have time.
