Because they are the ONLY company making a CSP switch that didn't have an agreement with EFILive to do so.
Ok, because switchable tuning does give EFILive and the tuners using it an edge (no pun intended) over people not using EFILive. I think it is our right to say who can and can't profit from our IP that we came up with. You know EFILive doesn't make one cent from a switch sold by SoCal or Startlite's app. But those companies invested in making a switching device (probably spent a fair amount of money doing it) and worst case scenario we don't want to see them coming out of China for $5 and they both get burned. Too much of that happens in the western world now and it is sad to see.
In the case of CSP5 switching they are far from that (on purpose), not so on the older GM VPW bus.
