The report this article is based on is actually called "On Thin Ice: Disproportionate Responses to Climate Change Protesters in Democratic Countries"

In my mind measuring the level of democracy is harder than the wealth of a nation.
There is a way of mounting a btrfs partition in Windows, but I am not sure about it's level of performance.
