@rufposten saw this yesterday, this graphic is utterly useless. Some country could have 50.0000001% Chrome use and still be bright green. It doesn't articulate whether Chrome forks such as Bromite or Ungoogled Chromium are included under the "Chrome" umbrella or not. Eritrea could have 49.999% Chrome use and be considered "free" using this infographic. It doesn't really tell you anything of value.
@rufposten there could be plenty more detail in this, I prefer to apply Hanlon's razor where possible but I have a feeling the lack of detail is intentional.
