I have worked at several places where SRE meant different things:

- A virtual, first responder team on call rotation for all the services because developers didn't want to be on call for their own stuff.

- Another name for a platform engineering / DevOps team.

- A team who built nothing, maintained nothing and were not paged for anything. They just collected metrics, built dashboards and spread the gospel of SRE with a big focus on form over function. IME they were annoying to work with, frequently missed the point specially when it came to stateful workloads and were ultimately just an incident factory.
