I get your point. But on the other hand you can look at GDPR and see after it that California passed the CCPA, Canada passed their own PIPEDA data privacy act, etc, so there is some precedent for other jurisdictions passing similar laws in the future. Companies and services that come out of this regulation may end up competing in the US anyway and creating a more competitive landscape there anyway, even if there is no DMA-style legislation passed there. We will see!
