We all have been guilty of making comments about ATC to the guy we're flying with like, "This guy is a moron" or "What is this guy doing?" However, they still have a job to do, and I would never make a comment on the radio like "anything else?" If the Eagle pilot was having a bad day and taking it out on ATC, it's wrong for him to do. I also don't agree with a person calling another pilot out on a public forum, like the OP.
