If it is for AWS resources it is not equivalent.

AWS don’t owe non AWS customers free certificates, though.

It is possible to host LetsEncrypt alternatives, though. The viability is another matter, though.

[pessimizer]

LetsEncrypt doesn't owe anyone free certificates, either. The point is that AWS isn't an alternative unless you're spending money with AWS. Nobody is wondering whether you can get a certificate by paying someone.

Equivalent in the sense that, if you're in AWS (which is a non-insignficant amount of people) then you have options other then Lets Encrypt.
