I can see what you are getting at. Reminds me a bit of their GTK theme Nimbus for the Gnome based Java Desktop System but also Bluecurve of Gnome 2 with Bitstream Vera. Perhaps it just looks dated?

Yea maybe I asked AI and it said the reason why is both Sun’s design and the Nokia design are both “a neutral neo-grotesque foundation, refined contrast, and consistent spacing”
