The most copied StackOverflow snippet of all time is flawed

6 years ago (programming.guide)

seems shallow to blame those copying SO when SO itself doesn't police input, and is actually blatantly in violation of copyright itself.

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?

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.
