Not entirely on-topic but I came across a very illuminating comment from the CEO of Namecheap:
Let's Encrypt. Ever going to roll it out?
I plan to switch away from Namecheap soon unless it's implemented, it's really disappointing to me.
and the response:
Hello Fej, to be honest, we signed an exclusive contract with Comodo before Let's Encrypt even existed. The length of that contract is ten years. It's put us in a tough situation as far as what we can offer out of the box to our customers. While our customers can still install LE on our hosting services on their own, we can't actively do this for them. The only other option here is to break that contract which will cost us millions of dollars and it's something that I continue to consider.
