Google stole open source code without crediting the authors (Artemis/Minitap)
This is a credibility problem for Google, not a legal one in most jurisdictions. Open source licenses vary, and if Google complied with the letter of the license, they're technically clear. But taking credit for others' work tanks trust with the open source community. For builders: audit what you're using and who's using what you built. For Google: this kind of incident compounds into a recruiting and partnership problem that costs more than proper attribution would have.
