The license says (paraphrased) that you need to keep the original license file, which has the authors name. Even if you re-license it, you leave the old license there without touching it and put your new license next to it.
They did not follow that clause and deleted the original license and the original attribution.

A thanks does not necessarily imply credit.
In that case, I firmly disagree with Blue_Morpho’s assessment.
