Somehow related is pretty far away from claiming they are the same thing.

First of all they're both consumer protection laws related to IT, which was my point that EU already has a track of enforcing these kinds of law, and it has nothing to do with one irrelevant lawsuit in the US.

But also GDPR is a law to protect customers data, after it was enforced and people saw the big companies were not untouchable other laws started to be discussed to further regulate them. Parallel to this the DSM was being enforced, part of which has the P2B Regulations, which regulates unfair contracts and trading practices. After both of these came into effect a new law, which is essentially the child of these two, started being discussed which would regulate how large companies corner the market and other abusive practices. To think that this law has nothing to do with GDPR but instead is because of a random lawsuit some random company lost in some random country is ridiculous.
