Re: Where it is stored doesn't matter?
As for your comment on Europeans using American services. I don't think I've ever met a European (and I'm European myself) who's rubbing their hands with glee thinking 'Gee, I can use this innovative American service without having had to put any work in it'. Frankly, most Americans won't have contributed to Google, Microsoft or Facebook either. They are just users.
I'd go one step further and say that they are quite a few Europeans that are annoyed by the fact that so many tech services are American and not European. Now, I think that is sometimes exaggerated. I recently saw figures for 2019 that made clear that almost 12% of all unicorns (tech firms with a valuation over $1 billion) are European. And that figure won't include companies that were European to start with and were bought by non-Europeans, think Skype, Skyscanner or Booking.com.
The big difference, I think, is that Americans are very good at running loss-making businesses. The US investment climate means that if you are successful, though loss-making, people will still queue up to bring you money. Case in point: Twitter. Ten years without making a profit yet Americans think 'if even the US president has an official Twitter account they must be on to something and they'll eventually find a way to become profitable.'
That sort of stuff is practically impossible in Europe. A startup will often need to show revenue after a year and most likely a small profit after two years. Now, for most startups having revenue in year one and a small profit in year two is very doable. Where it doesn't work is the massive free services where you spend the first five years giving your service away for free before you start to think about how to monetise your hundreds of millions of users. The investment climate in Europe just doesn't really cater to that. Hence, a service like Twitter or Instagram could never come from Europe.
And trust me, I think many Europeans find that just as frustrating as you do.
