« people who just want to change things for the sake of it » — Not for the sake of it, but to “make the world a better place.” The intention is noble (well, mostly, at least let's assume it is). Of course, there is disregard for history and her deplorables (or not so deplorables), comes with being “progressive”. Which is why I like Windows better (not 11 though, will probably have to go back to Linux at some point).

« What is it about these projects » — Maybe that they're “at the forefront.”
