Just to be clear: are you saying none of the information presented in the video is likely true?
Some of it is clearly true, like the stuff about Hasbro seeing D&D as under-monetized and pivoting towards new revenue streams with an emphasis on digital media. We also know that Hasbro had a rough year last year.
What I am skeptical about is the behind-the-scenes stuff from his sources. What he's doing there is essentially muckraking; he's relying on gossip from sources that have already been discredited by putting forth claims, that Will reported, which were subsequently shown to be false.
Had that happened to a legitimate reporter, they would have huge egg on their face, and have a lot of explaining to do to their bosses, because news media rely on their reputation. In fact, there's no way a regular news source would have got forward with the story about WotC not reading survey results, because it was just based on hearsay.
A reputable reporter would be extremely cautious about continuing to rely on those sources going forward, having been publicly burned once. Yet DnDShorts is acting like everything else
that those sources claim is reliable. That's bad journalism. You have to take the rest of their claims with a huge grain of salt until you can get strong, independent verification (which should have been done before the first story).
