If you’re not familiar with the memory hole, it’s when information starts disappearing. It’s happening again (it actually happens pretty often). See this post. If you follow up and check, you will see that the video is starting to disappear.
This is in part why my original post here (now password protected) was verbose and complete in its information. (A redacted version is now available here.)
Whenever information is sensitive, it’s a good idea to download it and preserve a copy in case it is needed at a later date. The censors and tyrants out there love nothing more than controlling information, and the less control we allow them, the better.
I will be uploading the speech from the link above to help ensure that there is no memory hole.
