I mean that the device is useless on its own, it needs a computer. When it was developed it was made to meet a certain criteria. Since then things have moved on and it's not viable to support it anymore.
In the last few years devices have been made class compliant, meaning that they don't nessecarily need drivers specific to the device.
I dont work for arturia, I moderate the forum for Spark, send in bug reports to arturia, beta test etc
