It sounds like you're referring specifically to Gill Sans [0], which is shipped with macOS and appears to be the font used on Edward Tufte's website [1]. However, it looks like Windows 10 now bundles Gill Sans Nova [2], although I'm uncertain how well it renders. Maybe instead of avoiding it completely, you'd consider suggesting a bundled alternative to use as fallback for other platforms? I wasn't aware of the font's existence before now, but I'm on macOS and I agree it looks nice on this platform. Personally, I'll typically disable remote fonts on my browser, since it just makes sites load slower. On desktop it's not as significant, but on mobile it's rather drastic. Sites don't have to render exactly the same on every platform and browser, it's fine, really! The Medium redesign [3] a few years back convinced me to try system fonts, and I've been really happy with the result. In case any reader is interested, Using UI System Fonts In Web Design [4] has all the info needed.
