Websites should set the base font size to the browser default, and scale that only for text other than body default: larger for headings, smaller only for truly superflous text, or notional elements such as super- and sub-scripts. Readers who are aware of the ability to set a browser-level font default will be annoyed at any other behaviour or choices. Readers who are unaware of that capacity, the overwhelming majority, are a lost cause regardless, but will likely use other mechanisms to zoom pages to a comfortable reading level. Otherwise, Air UI/UX are Beyond the Bend.
