Petitioning EU lawmakers would be better. American control of European data is already a bit issue at the moment in the face of US threats over Digital taxes and Microsoft being used to punish ICJ members.
EU (and the rest of Europe) are more concerned with controlling their own populations than keeping their data safe from the US. They are very much pro-big business dominance on the internet BECAUSE it makes it easier for them to regulate.
A lot of governments want to use American AI systems to run things to cut costs.
The EU is almost ready to sign off on Apple's DMA compliance as sufficient, despite sideloading being similarly restricted, and despite 15-20% commissions remaining. The DMA was never written to allow completely anonymous sideloading, or even commission-free sideloading, another law is needed for that.
