The first part of the video he take full responibility for what happened.
The opening cermony has always been something people could cover as it was not behind the paywall. The What’s next panels would usually have been behnd it and so in that sense they “knew” it was not okay.
I’m less than please that the official word on that being the case was posted in a place that not everyone could see it.
Like I said I’m looking at this myself, and quite possible this is something that winds me up because of my own history in corporate life. One to many managers that “forgot to clarify but you should have know” in the course of my life.
