Perhaps not coincidentally, these resins seem to be sold in less photogenic opaque black bottles, but this does make it more likely that a resin actually exists.
The part of the article that bothered me more was the explanation of the principle of operation:
At the bottom of the reservoir, there’s a piece of polarized glass which you place your phone underneath, facing upward.
The polarized glass then takes all this light (which shines outwardly to give your phone a wider viewing angle) and redirects it so that all the photons are traveling straight upward.
I don't think that's how polarizing filters work. But perhaps this is just an issue with the 3rd party reporting rather than with the product itself.
