Is that affiliated with raspberry pis in some way, or are they just freeloading on the "pi" suffix to confuse people?
They are "freeloading" indeed but in this case it is a valuable indicator that it should be physically compatible with many add-ons/attachments that are compatible with the Raspberry Pi.
