Compare this with Cloudflare:
1. Open website
2. See the IP 1.1.1.1. Copy.
Done.
I do get your point - and, sure, the EU website is not catastrophically terrible. But, damn, if I'm looking for a DNS, I just want the IP, I don't want five options and the mental overhead of having to determine why the hell I now am faced with five options for a DNS, which one I should choose, how they differ, etc., etc.. Add all of the IPv4/6 stuff on top of that, and.. oh man, I feel like you've lost 90%+ of interested people already.
