My ruling would be "I shouldn't have been put in charge of making rulings at the finals of the world championship".
First of all, to me it looks a lot like Bowen biffed a swift kick to his own jacket and caught the chair as well on accident. Chair fell over, Bowen put it all back. Nothing had a trajectory or got hit so hard that it came apart and had to be reassembled (#thekick), or actually just broke (#thepunch). I don't think it's that hard to discern the difference in intention in these situations, and I feel like the majority would agree. So yes, I would hand Bowen a yellow card as well if someone actually wanted a ruling.
Besides that, it's no secret that I err heavily on the side of "ticky-tacky". I only run small events that are mostly focused on being inviting to new players. I'm pretty sure KME is already hooked, so if guys at that level don't want to come, I'm ok with that, though I'd rather they did. I just don't want someone to attend their first league night, watch someone launch a chair across the room, and wonder why that was somehow deemed to be acceptable behavior by an adult in public. Stomp on your hat all day as far as I care! If I'm in charge, breaking things that don't belong to you is unacceptable.
At PAPA finals, no one's going to decide they'd rather not play because Bowen accidentally(?) kicked his chair over. To a new player in a small bar, stuff slightly more intense than that may discourage them from returning, if it seems like that might be the norm.
