In response to Cory Doctorow's powerful article, "Microsoft, Tear Down That Wall!", this post outlines the EuroStack Initiative's perspective. Doctorow treats our core mission—building a sovereign European tech stack—not as a fantasy, but as a viable project already underway. This shifts the focus to what he identifies as the next major hurdle: migration. Doctorow identifies the 'Berlin Wall' as the EU's own anticircumvention laws, and his analysis of the DMA's limitations proves why a legal right to portability is not enough. We must now champion the power to migrate by calling for the repeal of these laws, making it the essential next step to ensure EuroStack's success and achieve genuine digital sovereignty.
