…but then you can't claim that there were genuine, as Rossman did in his videos.

Do you have a link to the video? There is a difference between saying things like "manufactured to Apple spec" and claiming they were actually manufactured by Apple.

That's kind of ambiguous. He could mean original spec, as opposed to some junk using completely different components which is merely electrically compatible.

The fact that he's then comparing "original" with "counterfeit" goes against that a little, but it feels more like confusion than malice, or using the same word in two different contexts. Saying these are original-spec components without Apple logos and not counterfeit might be true even if the reason they're not counterfeit is that they don't have Apple logos rather than because they followed the spec.

There's nothing ambiguous about it at all, they are indisputably not original components even if they adhere perfectly to the original spec.

That's what I mean by using the same word in different contexts. Think AuthenticAMD rather than GenuineIntel. You have someone manufacturing components they're not claiming are Apple components, then they're original -- not original Apple, original That Other Company.
