Earlier quoted context omitted.
Who really copies stack overflow snippets verbatim? It's usually just easier to refer to it for help figuring out the right structure and then adapt it for your own needs. Usually it needs customization for your own application anyway (variables, class instances, etc).
Yeah! I've uh, ... never copied a bit of code into my repo verbatim, right? yeah right. I wish. (Not saying every dev does this)
But, I can't think of a single scenario where I've copied something from Stack Overflow. I'm searching for the idea of how to solve a problem, and typically the relevant code given is either too short to bother copying, or it's long and absolutely not consistent with how I want to write it.
