I'll admit, I had a similar initial reaction as you when I read OP's comment, but the perspective shifted once I actually read the post The post wasn't talking about his success, Rui was dissecting his company's _reason for failure_. OP took that and shifted the needle to point the blame for that failure to a different sector. He's not bashing on Rui, but that might not be clear unless one actually reads Rui's post! The only thing that might be questionable in OPs post is if there was any need to mention that he was Rui's director. The pros in favor of it is that it gave the post more credibility and attention (meaning it will help more people), and the con against it is that some folks might incorrectly interpret it as Rui-bashing and hurt OPs reputation. Given that the only people who that con would apply to would have no idea who OP was before this post (and are likely to quickly forget about him the next day), perhaps the director didn't choose poorly.
