I don't think any more formalization needs to happen for this stuff - the terms are already pretty clear. It's a matter of what is considered Fair Use and what is clearly an act of piracy. One only has to read the Terms of Use for CompTIA, On24, and YouTube to see this.
In my opinion (and I'm not an attorney, but I can read a TOU/EULA) it's not considered Fair Use for republishing a video because those are productions that were created by CompTIA. Between the licensing for videos hosted on On24, the Terms of Use for CompTIA to which every participant in TTT has to agree before joining, and particularly when reposting on YouTube under a different name, in this case, under African Digital University, it's not a gray issue at all.
An instructor downloading a PowerPoint presentation for his/her own use, or to build materials for a class, yes, this is a derivative work. But when you're taking a derivative work of a derivative work which has been okay'ed for public distribution - in this case, the Domain Objectives, permission has already been given for those derivations, although those objectives are still the copyright of CompTIA. (so a publisher would only have to cite that work in their derivation). Now if you use a person's additions to that derivative work, it's probably a good idea to reach out and secure permission anyway as a courtesy.
What we have here, in THIS case, is an entity wholly taking a work (a TTT session video) and reposting it without any indication of Permission from CompTIA AND under their OWN copyright flag. This would be a violation of YouTube's terms of service, as it's a pirated video - ADU had no right to republish the work if they didn't secure permission from CompTIA before doing so:
This is the same issue as if a college uses YouTube videos in their classroom materials. If the video is under the Standard YouTube license, it's a lot less murky than if you have videos that are licensed under the Creative Commons License - this requires the user to secure the permission of the owner of the material before using.
TL;DR - Secure permissions first before using a work in your class. Probably didn't happen here. But TTT instructors would generally have no issue with using their provided materials to build classes.
