The blog post is from a manager’s perspective. It’s a manager explaining what they had their employees do.
One thing I suggested was that they should be muted by default so that they aren't a distraction and don't set the expectation that they should be read.
I thought it would be interesting to write about because it was an emergent practice that seems to be sticky and useful within our team.
OP's post was about a great experience 'tremendous value' they had and now you're pooping on it with 'manager' opinions. Read what you wrote from the employee perspective, you're sounding like the self-appointed fun police.
Update: Cue the downvotes from the managers.
