A little bit more research and it looks like my analysis was a bit off-track (the files in question were never a part of Harmony)... and it also looks like this isn't exactly news, either.
This is merely revisiting
issues brought up back in November.
So, to amend my last post, it would be a good idea to figure out who supplied that code to the Android project... and when. If this is a case of decompiling a binary then mentioning the copyright warning isn't entirely relevant since that statement was from the source code, not the binary which was, ostensibly, decompiled. That doesn't make it any more legal but it does change the presentation of the issue.
It's also the one thing that open source advocates and opponents bring up... how do you guarantee the purity of community-supplied code? It's also a two-way street. Even Microsoft was found to have misappropriated some GPL code in their
Windows USB/DVD Tool. The fact that the source code for most commercial software is not available for public inspection makes it exceedingly difficult to identify those kinds of violations.
