Earlier quoted context omitted.
When you go to a restaurant you let the chef prepare food for you. Telling him to back off and let you cook because he can't know better than you (his user) would be absurd. Same thing with design and typography. It requires skill and taste, and hopefully people will be delighted or simply consume the content for what it is, because the design/cooking just reveals that content in a convenient/useful shape.
Most fonts picked by designers suck. Plain and simple. I override fonts for most websites I frequent.
I think most fonts that get your attention suck, the best ones are invisible and get you directly to the meaning of text, without getting in the way. So maybe there's a kind of bias (selection or sampling bias?) operating here?
