But Github's publishing is at least _highly_ portable. You could move the same web site to a vanilla nginx setup on some random domain.

The nice part here is that you can update your site via git version control, and have easy rollback etc... assuming you can deal with git.

I don't think it's such a problem to have big corporations involved in your publishing efforts; the problem is when they lock users in with proprietary technology, and create barriers to entry like high costs and technical complexity.

I don't have a need to mix anticapitalist fervor with the desire for an easy way to make durable, portable web sites. The internet has always involved paying some kind of piper. Corporations are too big & monopolization is a problem, but one thing at a time...
