I think that's a bit harsh. If you think the opposite - that MIT/BSD licenses should be preferred over Copyleft - then you should look in a mirror when saying that. Fortunately I suspect it's just your own preference and that's great. My opinion is that MIT licensed code is appropriate for some cases but I prefer GPLv3 as a default.

I'm rather angry at other licenses (MPL and Apache in particular) for existing. Maybe they bring some nuance that I don't understand yet, but their existence creates more options and concern over license compatibility. I think BSD/MIT or GPL/LGPL should be it, the rest IMHO are just fragmentation.

It is my personal preference. I couldn't care less how others license their own code. My issue is with people like those who came into this thread to complain about the license of a project they've contributed nothing to, and paint anyone who disagrees as a paid shill. If they want a rust-based copyleft coreutils, nobody is stopping them from building it.
