If other people pay you to be rude to them, that's between you and them. But that doesn't mean rudeness is welcome in all contexts, and this site is one where it isn't.
As far as the pitch, it seems to me that the video is the pitch. I'm sure if you were actually in a position to fund their work they'd be happy to talk it through with you in more detail. To me this system looks a lot less expensive than an exoskeleton, and is also much closer to practical realization.
So it's exoskeletons just around the corner.
And they can be carried around, so haven't to be build into that corner.
You may do your own cost comparisons for funding purposes considering the wider market for exoskeleton systems in logistics, construction, etc.
So this is just one example, there are a lot more different exoskeleton systems available.
Now I just have to look up, whether there are already studies, that tell me about probable health-promoting physiotherapeutic effects.
