Publicly. A Code and brotherhood to leave what's said in the locker room there.
I'm a big Poppinga fan, but I'm not sure why he choose to volunteer so much information about Staley in that forum/show, which is purposely formatted to be blue goggled. It's not like he was even answering a question. I suspect they won't have him back for some time, if ever.
Earlier this year JT went off about Mika. Although I think he was right in a lot of what he said, he realized it wasn't doing any good to bag on Mika and came back on shows to tone down his opinion and apologize to Mika. He didn't need to do that, but he was humble enough to. Poppinga would be smart to do likewise.
