Server Setup Information:

• Version of Rocket.Chat Server: 0.60.3 Merge pull request #9320 from RocketChat/release-0.60.3
• Operating System:m Linux
• Deployment Method(snap/docker/tar/etc):?
• Number of Running Instances: 1

Steps to Reproduce:

1. create new Channel
2. set it to public
3. enable write protection

Expected behavior:

Whenever the Owner writes something it will appear normally.

Actual behavior:

when you write something, rocket cat informs you it is muted

Usecase

Sometimes you have to send info to people without cluttering the #general channel, for instance like the whereabouts of devices checked out from the pool. so all know where to ask for it. You need no responses, strictly one way.

No file, test, or entry point is named in the issue. Reproduce the behavior by creating a public write-protected channel, then verify that messages sent by its owner appear normally rather than being treated as muted.
