> I seem to recall from other libre font discussions that @mbutterick (the OP) has something of an axe to grind about libre fonts in general, though I don't recall specifics.
He does believe that most of them are of sub-par quality and he has reason to be biased (due to being in the business of selling fonts himself), but also cites some counter-examples[1]. I don't think he's opposed to libre fonts as a concept.
Google employees have made a few really good libre fonts. Oxygen is my go-to font for almost anything design-related that I do precisely because it is a really solid free font.
