Positive about what?
You'll find in the 21st century safety managed environment, we spend a considerable amount of our time in training assessing other peoples mistakes and short comings.
It's how we learn. Everything in this industry, without exception, comes from a mistake or an incident and subsequently, an improvement to the practises to make it safer and safer and safer...
Whilst Im sure we'd (the ATCOs) all stick together in general, this incident shows (for whatever reason that you'll notice no-one has indentified or tried to) that this particular occurance was either embarrassing, dangerous or both.
Safety analysis and TRaining for Unusual Circumstances and Emergencies is part of our job. This isn't bullying the ATCO. This is assessing the actions - if I had an incident I would report it and it would be published and analysed for learning points.
It's how air traffic control is. So yeah, I've got better things to do but this learning point is justified in its discussion.
The first P in PPRUNE stands for professional.
Kind regards.
