I heard a good reason why some companies including Apple have this problem.
You can't actually get MORE money from the product.
Apple want to sell you a device, which it can then charge you more for as you use it, so first they sell you the item for a small profit, and then they use the device to get long term little payments from you.
With speaker stuff you can't really do that, all the money comes from selling you the hardware (you know, like the way the world use to be!!!!) so they are not really interested in supporting it much.
If they can sell you a device, and then generate long term ongoing money from you by you using the device, THEN see how much effort they put into it.
