GMX email: is this how Europeans think they can fight the dominance of American big tech?

I was curious about the possibility of switching from Gmail to a European provider for my personal emails. Many of the providers I found on european-alternatives.eu offer a simply risible amount of storage (often 1 gigabyte). The only provider that offers decent storage in the free version is the German GMX email. So, despite some alarming reviews, I decided to give it a try. Result? For two days now, registration gets stuck at the CAPTCHA stage with this message: "We're sorry, that didn't work. Please try again later".

If this is how European companies think to fight the dominance of American big tech, the latter can sleep peacefully.
