As much so as these kinds of OP's are.
If you're leaving, leave.
If you're staying, stay.
The rest of us aren't concerned with what you're doing, any more than we we're concerned with what you're having for breakfast or whatever other social media status updates you post. (Not a personal "you", but a general, blanket "you".)
Why did you focus on that part of his post and not the reason why ? What makes you think he cares whether you care or not ?
