The GDPR and DMA are mostly good. GDPR should have exemptions for organisations with smaller amounts of data who do not trade in it.
A lot of EU laws have also been bad. VATMOSS (especially with the very low initial limit to register) was initially a disaster. It actually deterred people from trading within the EU! The commission's attempt at chat surveillance was thrown out by the parliament, but they will try again. The new AI regulations look problematic. The draft I saw of the AI one was far too broad (included old tech like expert systems) - not checked recently whether it has changed. There are also issues with a lack of FOSS exemptions in the other current law (forgotten what it is called) imposing greater liability for faults in some categories of software.
