It's only Trump's America First policies that is pushing EU to react very late.
They can not even get intra European "talent" to do these jobs. Germany is notorious for its low level of digitalization and it's staggering lack in Software competency.
I think in general it's also the case that in Europe and the UK, technology has been a very upwardly mobile career path with many people who end up with good incomes but no familial network to fall back on and not accumulating any personal wealth or stability until they're already considering retirement.
This basically means technologists in Europe are not empowered to be entrepreneurial as bootstrapping is impractical around full time work and the investment often isn't out there.
Aversion to risk. No european company, bureaucracy, government is as bold and risk-taking as those over the pond. Only when something has been proven, stamped, certified and established, will it be used. So new and small OSS projects, startups, and generally new ways of doing things will have a far harder time overall.
There is even the tendency to spend tons of public money on stuff like GAIA-X to establish European cloud infrastructure. And then never using it because all that new-fangled stuff where one would be the first user cannot ever be good and viable. Thereby forgetting that money has already been paid to make it exactly like the European governments wanted it to be, and that any service needs its first users to grow over the teething problems...
And yes, now that America are showing their true colors with Trump leading the way, finally, finally we are starting to see that maybe this isn't how we should want things to be. It's still going to take a long time for Europe to shake off its dependence on the US tech industry and truly start to challenge it, but hopefully this is a wake-up call that will gradually push things in the right direction.
