Nah, the EU is being very aggressive with the DMA and DSA. See the whole Apple thing, Facebook delaying the launch of Threads in Europe to make DSA-friendly changes (mostly the ability to browse without a login wall) etc. All this for rules that have only been in force for a few months.
I think the EC has learned its lesson from the GDPR; “you might one day be fined, maybe in five years” (Facebook, say, was recently fined a billion of so for behaviour going back years) is not a sufficient deterrent.
At least in the EU those things are regulated, so it’s not particularly surprising the that the EU gets involved.
The speed is unusual, it probably would have taken month if this was American and not Chinese.
