Comparing this to Google Books is silly. Google stole copyrighted books. Copilot uses freely shared open source code. No copyright issue.
The article claims "Open source code on GitHub might be thought of as 'open and freely accessible' but it is not." Lol what? The MIT and Apache licenses explicitly allow reuse. Copilot can absolutely use open source data.
This is typical hype and FUD. No evidence Copilot even used all of GitHub's data or violated any licenses. Baseless speculation.
There's no real antitrust argument here. Nothing to see, move along. yawn
