GPL and derivatives are the best forms of FOSS licenses. I spent many years listening to views and genuinely did not find any strong arguments for using MIT/BSD/Apache/etc.

The most fundamental problem with most non-GPL licenses is that companies don't give back. Anyone who's worked in a corporate entity knows this. Some of the older BSD folks talk about Wind River a lot, and this is a company both my parents worked at for decades, and that company and their employees did not give a single fuck about BSD, beyond what they could take from it.
