But this is simply not true. MIT requires keeping the copyright notice intact, which would be a credit. People that aren’t going to follow this requirement weren’t going to follow the GPL or whatever alternative you pick either, so either sue them or don’t worry about which one you picked exactly.
If they redistribute the source then yes, but that’s not the concern in the post.
GPLv3, on the other hand, is much more explicit about saying that the copyright notice must appear in the actual user interface of the application.

The same question was posed in the comments on his article.
