Quotes from the book:
„Events are used for sharing information. In most cases, the application generating the event notification does not expect any response, and it lets the consuming application decide what to do with that information. Even if the applications generating the event notification expect a response, they expect it only indirectly.“
„Some events can be used to issue a command or enforce an action on other systems, such as sending an event to update Bob’s current address.“
Feedback: events by definition are never directed nor do they express or carry intent. The use of „passive-aggressive“ events to carry intent, e.g. „UpdateAddressEvent“ to signal the receiver to update the address of an entity is considered an anti-pattern and discouraged to avoid losing the benefits of the decoupled (space and time) nature of events.

First paragraph |

It should be "...then the consumer consumes that message..."
Later in the same paragraph has a similar error
"...The Producer uses that information to send..."
It should be "...The Consumer uses that information..."

1st paragraph |
the author said : "the producer microservice publishes messages to a queue in a message broker, and then the producer consumes that message from the queue."
for me this sentence should be :"the producer microservice publishes messages to a queue in a message broker, and then the consumer consumes that message from the queue."
