There are more ACME-compatible CAs than just Let's Encrypt, should they ever become the bad guys, or if you don't want to trust them for any reason, see [0].

I understand that people get annoyed at shorter cert lifetime, for instance if you are managing appliances or use SSL certs for other reasons than the common use case. But if you just want to serve a website, there are not so many reasons not to use HTTPS today, either on Let's Encrypt or on something else.
