No, a friendly request is done in private via PM or email and involves words like "please", "thank you" and "would you mind".
You have quiet friends.. ;-)
I still don't see the big deal with the initial request, even in public.
He didn't say "Hey, you're a thief! Take that down or I'll fix you!!!"
"Please, thank you, and would you mind" would have been polite and friendly.
That being said, the follow up, when he said he did that in that manner because of someone being a "vocal critic"... That's the type of statement that goes to intent, and takes the "leeway" out of the original comment.
I still think it could have been a friendly comment.
But I agree now, that it probably wasn't.
I still wouldn't call it intimidating or a threat.
But I would call it non-professional...
