Briefly, but all those dead links are now pointing to a message that says the video got removed at the behest of the company that made the movie, that's a negative experience.
Well, now that 100+ million people heard of it, it's a good time to pull the sample and tell them to go buy it (yeah, I know, but consider a conversion rate of 0.01% ...)
P.S. I don't really care. Just pointing out that this one probably ran its course, and empty links may make them more money than handing out lollipops. Or not. Not MBA'ing this.
I think you're missing the point here, that's not just a 'sample' but a reworking of the original, either with subtitles (most of them) or with a voice over (a very few, but some really good ones).
So watching the movie is not going to give back the parodies.
