This isn’t a good way to approach out of date information, you should always keep the conversation open in case people want to speak about how something may not work or how something is out of date, it’s easy to make a mistake, by closing the topic we mute the voice that people may want to use.
It’s to stop people from making unnecessary repeats or preventing people from missing an important piece of information. After a post with no activity after 30 days, it’s considered dormant, meaning it can’t be edited.
Now on day 50 @cookie makes an edit, keep in mind a user is not notified usually when somebody edits a post, the chance that you check the post or even notice the post edit is unlikely, therefore making a new post will allow the user to be notified about the changes.
It essentially prevents confusion & miss-communication.
