I know they had done a sponsorship before. This looked like they were using old material, maybe without permission to do an unauthorized ad run. Again, I'm not the only one in the comments of that post assuming this is fishy so that should tell somebody something.
There's no evidence of that though, and they are using an old photo, and they don't link to him in any way, they only mention his name.
Irrelevant for reasons I explained in other posts. This could still very well be unauthorized. And to be frank, you posting a video from 2017 sort of lends credence to suspicion. If that's the newest mention of this product then it most likely IS unauthorized. Ironically, you were the only one who drew any conclusions here.
