DMA has not been used against EU tech companies because US tech companies are clearly the market leaders in the area the DMA is concerned with. The DMA exists to make sure that companies (from the EU, US, or elsewhere) comply with EU regulations regarding privacy, tracking, and consumer rights.
It's not a "tax" on US companies, it's just that US companies don't bother to comply with the regulations that apply in the EU, and thus get fined.
Explain why Spotify got a carve-out from the DMA despite being an effective monopoly gatekeeper.
Is it because it's an EU company and the DMA is a tax on the United States?
'The law that applies only to US companies is applied equally and fair!'
>US tech companies are clearly the market leaders in the area the DMA is concerned with.
There's a good argument that this is targeted. Why didn't this regulation affect SAP? Their market position gives them leverage over a massive number of companies.

It's not that they "don't bother", it's that they understand complying with the regulation to cost them more than the fine. In other words, the regulation itself is a sort of fine, or tax imposed by the EU, with a magnitude of roughly equal proportion to the fines it imposes.
