I'd ask the inverse of the question: morally, should a single gatekeeper have the right to deny two consenting parties the ability for one to run the other's software?

Especially when that ability has been established practice and depended upon for decades? And the gate-kept device in question is many users' primary gateway to the modern world?

There's nuance here, of course - I'm not morally obliged to help you run Doom on your Tamagotchi just because you want to do so. But many people around the world rely on an Android device as their only personal computing device (and this is arguably more true for Android than it is for iOS). And to install myself as an arbiter of what code they can and cannot run, with full knowledge that I could at any time be required to leverage that capability at the behest of a government those worldwide users never agreed to be dependent on? That would be a morally fraught system for me to create.
