I absolutely adore what Let's Encrypt has done for the Web, and I proudly wear the hoodie they gave my company for our sponsorship. It's amazing what a company of 11(?) people can do, most of which probably don't even do any development.
However, I really think that they need some (free) competition --- their market domination is becoming a little extreme. Someone else offering free certs via the ACME protocol would be nice
Obviously this is really great in every respect, including a potential opportunity for finding compatibility bugs with ACME implementations.
So perhaps what you were hoping for has already happened!
(Edit: also, thanks for your support for Let's Encrypt!)
(Further edit: apparently the BuyPass ACME certs are valid for 180 days, as against Let's Encrypt's 90 days, but only let you list approximately one domain per cert, as against Let's Encrypt's 100 domains per cert. https://community.letsencrypt.org/t/acme-sh-supports-tls-alp... It's still awesome to see more options for ACME support and definitely makes it more credible that it wouldn't be as serious a problem if Let's Encrypt went away some day for some reason.)
