Fair enough, if you only want to avoid Google for the hosting you could just copy their fonts and be done with it, yes.

(And in my case that whole effort wasn't actually so much for philosophical reasons, i.e. to try avoiding to use Google at all costs, but rather because Google Fonts was serving an outdated version of the font I was wanting to use, and was missing either some additional characters or bug fixes that were only added in a more recent version.)
