I have to question the overall quality of the article when it repeatedly uses the term "channel" to refer to the well-established concept of a "topic" in MQTT.

I'm not very knowledgeable about MQTT specifically, but it seems like fair game considering the protocol spec (https://docs.oasis-open.org/mqtt/mqtt/v5.0/mqtt-v5.0.html) uses the term channel:

> 3.3.2.1 Topic Name

> The Topic Name identifies the information channel to which Payload data is published.

I have to question your overall understanding of the topic of message passing. Channels are a well-established concept in messaging.
