The person I was replying to said they had no idea how it had anything to do with PowerPoint. The article quotes the report as identifying over-use of it as one of the problems that contributed to the communication break down.
I'm not making the argument and I'm not interested in engaging with this quibbling, I'm just explaining how the article said the expert who conducted the investigation found a problem with their use of PowerPoint. If you have a problem with that conclusion, then take it up with the investigation report, not me. I would be fascinated to see you provide a rebuttal of it.
