Birchler points out that the banks did do this.
And Gruber has acknowledged his mistake.
Gruber is an open fanboi but for the most part he would at least get his facts straight and would be open about what he didn’t understand and would link to experts in the field.
However, since the EU DMA actions on Apple he seems to have completely lost his objectivity. First by pretending to understand the legalese better than apparently the EC does, then by applying American lawmaking approaches to European ones which are very different and then finally by taking Apple’s bad faith statements at face value (Gruber’s turn has coincided with Apple’s very weird bad faith approach to the EU so maybe the fundamental issue is his trust in Apple).
And he seems to be carrying over that to the U.S. govt’s antitrust action as well.
Also, to be fair, social media is absolutely filled with Apple people pretending to be legal experts but being completely wrong about almost everything. So it might be hard for him to even see opposing viewpoints from legitimate folks.
