[deleted] Aside from the fact that you think closed source code cannot be inspected, which is false, it simply doesn't matter for what I'm trying to explain.
Regardless of the app's source model, it's still constrained by the same rules. The sandbox is open source, what apps are and are not allowed to do is open source, it's known, it's not an unknown thing.
You can use whatever you want, but let's please try to maintain accuracy when discussing these topics that are so often subject to misinformation.
edit: just noticed a fellow mod had already replied.
