To my eye, those are distinctly different connectors. The linked device is using a novel wire connection method to a conventional banana plug. The other using a spring-loaded pseudo-guillotine connection designed for bare, or perhaps tinned, wire.
The SpeakerSnap would appear to borrow heavily from WAGO idea of wire connection, which in most jurisdictions is electrical code approved. Doesn't necessarily make it good for audio signal connections but is not without precedent.
