US admin is threatening the EU on multiple fronts if you haven't reading the news. Invasions of sovereign territory, dismantling the EU etc.. This is unprecedented and without merit and a lot of EU citizens and governments have reached their patience threshold and are choosing to buy elsewhere.

The US has simply casually mentioned they could turn off all access to US digital services and products that we currently pay good money for. The concern is that they might maybe not all at once but I'm not waiting to find out that they're testing the waters with a single provider.

So we're getting security and independence and promoting the EU tech scene! EU has better privacy laws as well. Before this the US was seen as a reliable ally.

It was a mix of stubbornness and curiosity how far you could push this experiment.

Can't speak for the author, but freedom from US spying ideally. Additionally, not providing any revenue to a US-company that in turn pays taxes to a government that they don't support the actions of.
