I'm kind of confused as to why they don't have a demo showing all the fonts. I'm not just going to blindly pick from system fonts, I want to choose which I prefer first. Yeah I could look them all up, but just seems like they missed showing off the core thing...
That’s not the point. This is supposed to be a stack that gets you the system font on Windows, Android, Apple platforms, and maybe Ubuntu. It looks the same way the rest of the OS does, unless the user did something weird (eg. install Avenir on Windows).
I'm guessing license issues would be a problem. Roboto wouldn't be an issue, but I'm pretty sure Microsoft's and Apple's default font files require a license to host.
