Is code posted on SO under a license or something? I don't appreciate the wrong doing here --that the author of the app didn't understand what he copied is an assumption.
Yeah, I had the exact same reaction. Stack Overflow is used by a huge chunk of developers, so the headline isn't the least bit surprising.
This sort of feels like a "gotcha" -- a headline that's trying to make it look like someone got caught doing something wrong, in the hopes that the story will go viral.
All user contributions on SO are CC-BY-SA 3.0 licensed.[0] This actually makes it difficult to incorporate into larger programs that are licensed any differently.
Copying and pasting from SO is perfectly acceptable as long as you know what the code is doing.
When I paste code, I include a comment with the link back to SO. I see it as the standard way of declaring a precedent in programming, where upvotes signal strength.
