from what i gather, it looks like they saw the 'q' in rabbitmq and thought 'ha, a queue we could use.' totally ignoring the 'm' part. the blog post doesn't say much but it's obvious they were not sending 'messages'. a message is a specific thing, it contains information that is meaningful to the recipient[0]. or perhaps rabbitmq has allowed itself to be drawn into all sorts of use cases (as a result of competition with kafka)? a message should be very small, immediately ack-ed or rejected (i.e. before any processing begins). that's why rabbitmq assumes it can run entirely in memory, because messages are not expected to stay in queues for long (i.e. during processing by recipients).
