I can’t speak to the specifics of the DMA, but the very nature of regulation that leaves anything open to interpretation is risky for a regulated entity. As a developer of regulated software, I would be flummoxed with a request (a) make sure I comply with the law, (b) account for the fact that the law leaves sone things open to interpretation, © I am expected to use my understanding of the law’s intent when interpreting the law, and (d) if I fail to correctly account for the intent of the law, then I will be heavily fined.
