The major cloud providers have options for free certs: Amazon and Google run CAs, and Azure has an option for free certs from Digicert. Amazon and Azure both work with their services. Google just announced they’re supporting the same ACME protocol that Lets Encrypt uses too! It is somewhat important for Let’s Encrypt to have competition: For reliability it is good to have alternatives with no shared infrastructure. If Let’s Encrypt ever becomes untrustworthy (and as a LE employee, I hope that never happens!) there must be alternatives so the root programs have the option to remove the Let’s Encrypt root. And there’s many geopolitical concerns too.
