Hold up. I can't make an app for you because that asshole over there says no? Refund that shit. The hardware clearly isn't yours, so your money should make it's way back to your wallet.
Where does it say that you can't make an app? From my understanding, you can't distribute in their store. Nobody is taking away your hardware or blocks you from using it.
Meta/Facebook has the quest locked down so you can't easily install run apps without using their store. By preventing developers from releasing new games/updates on the store for quest 1, they've effectively killed the product.
Its the same as if Apple stopped supporting an iPhone in the app store. That phone is no longer able to install any apps on it.
