A point of contention for me is the IEEE Code of Conduct [1] whose point 5.e. can be summarized as "I will not infringe the intellectual property of others". If you are critical of copyright itself (something not unusual among hackers) then the IEEE may not be the association for you.
That seems to be a small minority in software. 2% of Github repos are Unlicense licensed, 16% are something else I don't know and for everything else, the authors have chosen to use copyright to restrict how others can use it in some way, even if it's just keeping their name on it.
Usually that only makes sense if other people's use of it makes it harder for you not to. For example, you can want a 4-day working week but still work 5 days because you'll lose your job to a 5-dayer if you don't. But if it was forced on everyone, you'd be happy.
Violating other people's copyrights while still exploiting your own probably means you just want to pirate stuff for your own selfish reasons. If you were against copyright protections in general, you wouldn't be choosing MIT or GPL for your open source code.
