As I read the article the issue is not the license. The issue is (allegedly) stripping the copyright information. If you use code under any license you get a permission from the authors to use it under the given terms. The authors still retain the copyright and most licenses require you to retain the copyright information, some even to display a prominent notice. This is important if the project ever chooses to relicense - they can’t just change the license of code that they don’t have the copyright for. So, if you ever use code from someone else, track where it came from.
