Currently, we load fonts (Noto Sans) directly from Google Fonts CDN, ref: https://github.com/ezsystems/ezplatform-admin-ui/blob/1.5/src/bundle/Resources/public/scss/ezplatform-bootstrap.scss#L1. 

To avoid having to accept Google data processing contract it should be bundled. Licensing isn't holding us back either, ref: https://fonts.google.com/specimen/Noto+Sans#license.
