You are correct, a better description is that their path to 'deliver exactly once to the best of your ability' is clearer.

If I remember correctly SQS is hard limited to a fairly short timeout to requeue messages delivered but not acked. In rabbit it's much more configurable.

Also regular rabbit hosts support the kludge pattern of, 'just run one host and accept if it goes poof you can lose messages,' which is useful if you don't want to bother with the complexity of clustering or are on a shoe string budget.

Lastly you get a nice user interface with the management plugin and you can stand it up locally with docker compose (without depending on AWS for dev or any of the 'aws but on your laptop' solutions).

Yeah, those are nice features to have. Plus you don't get the platform lock in.

Normally I don't give a crap about vendor lock-in, but this would be an exception where I'd agree with you.

Though most people are just going to use a framework plugin to manage the messaging layer, so what's behind that is largely irrelevant.
