I still see it.
Besides, doesn’t retweeting make a copy?
Interesting. At the link for the Twitter feed, I see the "Something's wrong" blue screen on several of the tweeter's tweets.
Don't know much about tweeting (hate reading in dribs and drabs!) But, I do know that (1) tweeters can take down their own tweets, and (2) Twitter can take them down too. I thought for a taken-down vid to persist someone had to download it, i.e. make another copy of it somewhere else.
