I've just read the AVH report.
On the audio referenced by our competition there were background sounds during the transmissions of EI-433, one being an autopilot disconnect wailer, on the next transmission a "Traffic! Traffic!" TCAS Traffic Advisory. In cross checking the recordings we found the actual communication between ATC and the aircraft, as recorded by that video, confirmed, however, none of the background sounds was available in any of the recordings we got hold of (including those of LiveATC), neither the autopilot disconnect wailer nor the Traffic Advisory were present in any other recording. It is interesting to note, that by Feb 14th 2017 the "Traffic! Traffic!" sounds and transcript were removed from the video referenced by our competitor.
It may perhaps help to understand the motivation of the video author: On Feb 12th 2017, after first analysis of the radar data, we posted a comment under the video stating the facts as revealed by the Mode-S data. As immediate reaction the video author disabled the comments under his video, thus also removing our comment from public view (the comments were re-enabled by Feb 14th). A short time later on Feb 12th ads were activated on the video obviously to monetarize the video.
Update Feb 14th 22:09Z: Following the release of our coverage the video author has removed the video.
There are some knuckles to be rapped I think.
