This is an interesting point.
The word fault somehow implies that something’s wrong - from the eu regulator’s perspective, what’s happening is perfectly normal, and what they want : at some point, the advances in insert new tech are not worth the (social) cost to individuals, so they make things more complicated/ ask companies to behave differently.
Now I’m not saying the regulations are good, required, etc : just that depending on your goal, there are multiple points of view, with different landing zones.
I also suspect that what’s happening now ( meta, apple slowing down) is a power play : they’re just putting pressure on the eu, but I’m harboring doubts that this can work at all.
