Just went back to the site and the video is still on his website.
Yes, it finally is. (Again, not still.) It makes sense that he would replace the YouTube one with one that’s not going to go away.
For those of you wanting the easiest way to download “Absolute Proof”, I recommend the Gab link
https://tv.gab.com/channel/realmikelindell/view/absolute-proof-601d73a5a5ca1b4ef4f0e602
... because you just right-click and save. It is already an .mp4 file, so no special download converter, app or link is needed.
