‘ Schwab has repeatedly called for the need to limit the scope of the DMA to non-European firms. In May 2021, Schwab said, “Let’s focus first on the biggest problems, on the biggest bottlenecks. Let’s go down the line—one, two, three, four, five—and maybe six with Alibaba. But let’s not start with number seven to include a European gatekeeper just to please [U.S. president Joe] Biden.”’

Intentionality seems pretty clear and this guy is highly relevant to the crafting of DMA.

It’s just an approach to procedural lawmaking that is somewhat foreign to American minds that are used to ‘bill of attainder’ style concerns.

He didn't suggest not to include a European company to protect it but rather it shouldn't just be in there to placate the US. That is different from it should be in there but we keep it out to protect it.

If you read that and come away thinking there aren’t protectionist impulses at play, I don’t know what to tell you.

There probably are, but my guess is that they are secondary to just not wanting "that stuff" in the first place.
