So you are claiming that reason of very existence of Google Fonts is to collect not-so-useful-and-easily-could-be-collected-by-other-services-of-Google data? Can we stop the whole Google bashing it is getting ridiculous.
They are an advertising company, which pretty much makes them data collection company. Its completely fair to question their motivations.
"A web with web fonts is more beautiful, readable, accessible and open. " Google Fonts makes it quick and easy for everyone to use web fonts, including professional designers and developers. We believe that everyone should be able to bring quality typography to their web pages and applications."
If you have some actual evidence that the last part isn't true, and that it's really some big scheme to "log visits", what is it, exactly?
FWIW - my dealings with the team, which mostly involve reviewing occasional open source font contracts, makes me believe they really are just crazy about making web typography good. But i'm really interested in whatever sinister theories people have.
I mean, you know what they say about people who like "Signika Negative".
