That’s not true at all LOL. Stack Overflow is my #1 visited site at work, and any good programmer uses it. Computer programs are inherently unique, so you can’t just copy entire file directories from SO, but any time I’m trying to do something and I don’t know how, I look it up. Chances are I’ll be able to find an answer with code samples from SO that I can copy into my program and tweak/customize to get working. It’s not plagiarism, it’s knowledge sharing. Taking an entire program and source code is plagiarism (all SO code falls under a version of the Creative Commons License, if you’re curious you can look it up), but a function or handful of lines isn’t unique IP, it’s a way the language provides to accomplish one specific coding task.
