The device tree is supposed to be provided by the boot loader, which in a typical ARM environment is supplied by the system vendor.

in a typical ARM environment the entire OS is provided by the system vendor, that's not a very good argument.

ARM vendors don't really care about Device Trees, they are pretty happy just hard-coding the kernel itself.

it's the people who want to upgrade the devices and people who want to maintain the upstream tree that want the consolidation made available by device trees.

ARM vendors may care about enumerable device information if they are targeting general purpose Operating Systems as opposed to the existing tight vertical integration process.
