I think ownership here is not always bound to making money off it or a third party making money off my content. There are various reasons like control over content as well as privacy aspects, which all play into ownership. So the Author only really does not like someone else making money off of his work it seems.

I have my own reasons (lesser around monetization) and thus I'm hosting some of the webservice I depend on on my own for some time now. Since I am not very much into sysadmin things, I found https://cloudron.io recently which has served me quite well thus far. Looking forwards to eventually get my email on that as well :-)
