I'd love to hear your reasoning why people who aren't European would prefer to avoid European service providers.
I'm generally a Hetzner fan as well for global services, but I can see the point in avoiding Hetzner (for example) if all of your users are in the US, since Hetzner only offers dedicated servers located in Europe (Germany and Finland if I'm not mistaken). Generally you want users to hit servers that are close to them, so something like Vultr would be better if the scenario mentioned before applies.
