This is only true because Apple dictates it to be so. The manufacturer of the device should not have a say in what I choose to do with a device I bought. I should be able to install software on a device without asking the manufacturer for permission. Why do they think they should have an opinion? After I purchase the device, it's mine, not theirs. I can throw it off a cliff if I want without asking for Apple's permission, why can't I install software on it?
> At that point, they _do_ want a relationship with some hardware manufacturer so that the third party app can be delivered to run on the hardware.
The device manufacturer should not need to be involved with a user's decision to install software. There should not be this requirement to have a relationship with them. We should never have allowed this idea to be normalized that the device manufacturer needs to be somehow have a say, let alone be the sole path to using the device.
Device manufacturers should sell devices and then get out of the way of what the user is doing with those devices.
