i think that FOSS should focus on freedom, infectious (copyleft) licenses force developers to change the licensing on their own code, thus acting against freedom same thing with the forced attribution found in many licenses (even "permissive" ones) FOSS in my opinion should be about releasing code to the public without expecting a return (modified code/attribution) or imposing rules (forced license change) that's why my favourite license is the 0BSD (also submitting the code into the public domain, in applicable regions)
