What happened with MTV News had happened with some of my film reviews posted 20+ years ago at Usenet groups and later having been linked to IMDb and Rotten Tomatoes. Few years ago I started noticing that some of the links simply disappeared. It isn't uncommon. There was, IIRC, an 2016 newspaper article claiming that more than 50 pct of all links in New York Times from 1996 onwards became dead links.

In my particular case, it was very annoying, because I relied on those articles being available as reference for later reviews. Google (which took over Usenet via Google Groups) and Amazon (which took over IMDb) apparently decided to save on server resources or in some cases those reviews slipped into memory hole.

This was one of the reasons why I decided to re-post those reviews on Hive blockchain, because it proved much more reliable.
