seems shallow to blame those copying SO when SO itself doesn't police input, and is actually blatantly in violation of copyright itself.<p>one example is the 2nd most popular question about inputstreams and strings. that #1 answer is itself lifted from an Oracle blog which, from what i can tell, has no license and so is basically unusable from a legal perspective. it could e.g. only be usable for educational purposes, non-financial, or only by Oracle employees. who knows without a license?<p>it's goofy and inappropriate to think that its license somehow "infects" the content and turns it into CC-by-SA or whatever it is.
