I remember, weeks before the ONE D&D announcement a Mike Shea blog post and Ray Winniger giving a thumb up.
Dungeons and Dragons future? Ray Winninger gives a nod to Mike Shea's proposed changes.
One of the point was an updated SRD. So I think that the OP youtuber did the stunt to get some clicks. Remember that the original 5e SRD has the "old" races rules, and one the things WotC want to do with OneD&D is to create a new "accetable for everyone" D&D, so at least those rules needs to be updated in the SRD. Update this, update all. Maybe the rumor (if ever existed) is that the SRD will offer a lot less content of what is offering now?
