While I would agree that overall repair-ability isn't great, you're wrong. Replacement controllers are available without an issue directly from meta:

On the software side they have been pretty great with support IMO, e.g. by adding 120Hz to the Quest 2 quite some time after release and opening up the Oculus GO, after they discontinued it. Maybe not valve-level but definitely much more than I expected from meta, and their hardware was a third of the price of valve's, despite having an actual APU in them!
