Silicon Valley has an 'unfair advantage' in terms of capital available and the talent pool (though the latter is changing). This means that if you're going to roll something out you have a very good shot at cleaning up the EU market besides your home market because you will have the ability to massively undercut any EU competitors to the point that it would have to be an existential risk (after all your other EU competitors can do the same) to not do business with the US tech giants.
That's not spinelessness, that's sheer survival in a world where the table is massively tilted.
Breaking US dependence means breaking SV dependence and that's not even something the other states in the US have been able to do (Seattle got a head start and still didn't manage).
The same goes for the rest of the world...
Now, as to whether or not the EU could do better: so far, not really, because the main reason the EU does what it does is because it is a strong subscriber to free market principles, both within and without (and for better or for worse). The US has now burned a number of bridges which for most people in the EU (present company apparently excluded) were beyond the pale not that long ago.
So the tide is finally shifting: doing business with the US for critical services is now seen as a massive liability. This opens the door to local competition but that local competition still has to deal with various realities: environmental laws, anti-competitive legislation (which is stronger than in the USA) and a fractured linguistic environment as well as a lack of available capital. Those are - each by themselves - massive challenges that will need to be overcome.
I'm too old to take the lead in any of this - assuming I even could - so I'm happy to stand back to see what is going to happen and to help people see what is to their advantage and what is not. But I'm going to reserve judgment because I think that if you want to solve a problem you're going to have to work with people rather than to blame them for any of the ruts they're in.
