Based on my cheatsheet, GNU Coreutils, sed, awk, ImageMagick, exiftool, jdupes, rsync, jq, par2, parallel, tar and xz utils are examples of commands that I frequently use but whose developers I don’t believe receive any significant cashflow despite the huge benefit they provide to software developers.

The US didn’t even get the excuse of being forced to pay obscenely high war reparations to justify their fascism. Instead, it’s dissatisfaction with inflation which, in turn, is the predictable combination of the exponential depletion of scarce resources (real estate, water) and the consolidation of property into the hands of an ultra wealthy minority. If one must frame the emergence of fascism in a “war” context, then the cause is plutocrat beligerantes strategically fighting a social class war while most of everyone else think it’s a culture war.
