M. Snoep, here.
I agree with the article on almost every point, but I find the argument that market power can exist and be maintained without anti-competitive practices rather unconvincing, especially when applied to the DMA. In reality, such a notion is more of a legal fiction: either anti-competitive behaviour goes undetected, or – more troublingly – antitrust laws are not enforced, often due to a reluctance to act or the perception that enforcement is largely ineffective.
