I don't think in India, where Browserstack is based, Whistleblower laws are that strong, the false claims could often be masked as a "flaw" and a bug rather than by design, and hence not sure how it plays out, but I think from the looks of it, if it is an ex-employee, that person is at a riskier position.
Was wondering if this is instead transformed into a wireless "near-fieldish" charging solution. Where you keep your phone on top of a speaker, then realized that the article assumed only 50% loss because of air, and in fact you can't even physically focus a 1m^2 speaker at near field.
That seems like an awfully Rube Goldberglike way to charge you phone though. If you're putting it on top of a speaker, why not ditch the speaker assembly and just keep the coils and there you have an inductive charging mat.
