So, this chart from Statista is wildly, wildly wrong. But really, why would anyone trust automatically aggregated data that doesn’t give a source? https://www.statista.com/statistics/330695/number-of-smartphone-users-worldwide/ …
Do you think this makes the service not useful? Easy to browse data with links to primary sources you can vet still seems valuable even if some of it ends up being questionable. Similar to building up surface knowledge with Wikipedia.
