There's always https://www.terraform.io/ to guard against vendor lock-in, but then you're still stuck with another vendor if you decide to switch.

Moving a TerraForm managed infrastructure, which has higher complexity than one ec2 instance, to another provider basically means rewriting most TerraForm code. I don't see TF to lower the barrier of vendor lockin really.

Completely agree, Terraform doesn't abstract away the cloud specific bits, it pretty much exposes the raw resources.

Terraform is "multi provider" not "provider agnostic".
