The people in the story will still know who they are, and anyone who knows that they work with Sebastian will know too. Yes, if they get upset, it's "their problem", but "their problems" become "your problems" if it affects the relationship.
I posted a blog entry about some code I'd inherited from a friend. I posted a problem I'd found (really wasn't even his fault specifically) and my fix. Very matter of fact - I wasn't a joker about it. He still read it, saw himself in it, and saw it as a public shaming, even though the client wasn't mentioned, nor was his name mentioned.
Yeah, I can say it was 'his problem' in how he chose to deal with it, but it strained a friendship if nothing else.
One one is being publicly shamed. From the article:
Names and details changed, for obvious reasons.
