Posting this as it seems the researcher is scrubbing all information of his findings off the internet, likely because of legal threats from Flock.

I hope someone has archived the video or github repository, and would be willing to share a reuploaded copy.

Wasn't able to find it with https://findyoutubevideo.thetechrobo.ca/ unfortunately.

The YouTube video was available at the URL:

and the GitHub repository was at:
