I think part of the problem is all the channels is has to go through. No idea on this mod, but I know mezel mods made some mods for them in the past. So, now you have a 3rd party making them and needing to get paid, you need to get paid and now distros need to get paid.
Glad they opened the Stern store as I don't think the smaller run and pricey accessories arent really supported by a distro system.
