It is all about the implementation. Just today I had a manager, remind the developers who were talking too much that the meeting needed to be over in 15 mins. Horrible long meetings is a culture thing.
Blaming someone for something because they left early is a culture thing.
Managers sitting everyone standing is a culture thing.
Scrum is a tool. You can use it badly, and horrible cultures will use it badly.
Your logical fallacy is: No True Scotsman. http://rationalwiki.org/wiki/No_True_Scotsman

That's why I put that "allegedly" in there, along with links to where the claims were made.
I see these claims in the business press from time to time, but I rarely believe them.
BS reporting is a catch-22. Since I repeated the claims, I get well-informed debunking. If I'd ignored the claims, I'd be getting poorly-informed debunking from people who saw it and believed it.
I'm pretty happy to get well-informed debunking, rather than poorly-informed debunking.
