Isn't this the exact opposite? Zoom didn't bother to go get accepted into high requirement locked down garden, instead they choose to distribute the binaries on their own without having to deal with pesky rules about unsigned scripts.
Well, if it was only possible to install apps via the App Store (Apples wet dream, but they'll lose a ton of users), then Zoom wouldn't be able to distribute their app any other way and forced to follow the guidelines.
Again, I'm playing devils advocate for a pro-walled-garden opinion me myself don't believe in, so don't take my opinion too seriously.
It's not an either/or. You can simultaneously have more trust in apps coming from the walled garden and cherry-pick with greater care the select number of potent applications that come from outside of it and are therefore harder to trust, precisely because they may be able to do more than what's allowed within the walled garden.
