It's better to block web fonts with uBlock Origin. It would be sweet if someone could add support for these fonts to Decentraleyes as well, which seems to be missing. Seems to be some debate about the merits of doing so, however: https://github.com/Synzvato/decentraleyes/issues/34
I'm okay with 1st party usage, but I don't want Google following me around the web.
Mozilla (and Chromium) could mirror Top X Google Fonts directly into the user's font system and entirely eliminate remote calls for a small size increase in the browser installation.
(Or Microsoft and Apple could do it in OS images.)
You can do it yourself, even, but unfortunately font loading timings are a deanonymization vector with its own privacy implications and it would take a concerted group effort to install similar font sets locally to avoid those privacy issues.
