I don’t know the marketing reasons behind hall effect keyboard v/s magnetic keyboard, but a technical reason for calling it magnetic keyboard is that they are probably not actually using hall effect sensors. Hall effect sensor is commonly used to refer to any magnetic field sensor but there are many others types. Given the size of the keys I suspect they are actually MEMS Lorrentz force sensors, so “magnetic keyboard” might be more correct. https://en.wikipedia.org/wiki/MEMS_magnetic_field_sensor https://en.wikipedia.org/wiki/MEMS_magnetic_field_sensor
