Hi flatsurf,
Welcome to the daylight.
It is not normal to verify information with Wave before posting it. Nor is it necessary afterwards.
The video is still publically available via the internet.
It is displayed on Wave's own YouTube channel with various other videos.
It may be embarrassing to Wave that it has posted a video it didn't intend to. I understand.
But the video itself discloses the use of an Android mobile app using Samsung hardware (the Galaxy Tab, a Samsung PC and a removable SED/SSD). It is based on proximity control over a Bluetooth network, using Wave's ETDM and its authentication software. This information is all incorporated on YouTube.
Not sure how much of this Wave wishes to deny, although according to the message you have heard, it seems they are attempting to deny certain things which appear manifestly to be true. Time is an arrow, even when Wave itself appears to have made a mistake.
