This is why I never even started using Letsencrypt; looking at the fine print, you actually enter into some kind of contract with some US entity under US law, which I don't want even if it's the coolest of all FOSS foundations.

Here's a site that has some info:

I have used certum.pl for years and it looks like I might go back to them soon because my VPS provider doesn't offer bundled certs anymore.

I used to pay €40/year iirc.
I suspect it's gotten more expensive though.

edit:
oh looks like ZeroSSL are doing it letsencrypt-style with Acme protocol for €0.

edit2:
No, not more expensive. Some of the providers in the above link are labyrinthine and I couldn't even find a Pricing section - usually a sign that it's too expensive at least for a normal consumer - but others offer yearly certs for as little as €30 (taxes not included).

edit3:
Yeah some people are going to have a hard time accepting that a contract with a for-profit company under EU jurisdiction might be preferable to a contract with a non-profit under US jurisdiction.
