This kind of thing is why I insist on using Reddit via mobile Web instead of their app, no matter how much they nag me to switch. Native apps allow lots of invasions of privacy like this. Web apps inherently don't, and they can still do everything that I'd want for sites like Reddit.
The problem is that you cannot lock down the browser either.
You can deny some sorts of things, but -- and this is all apple -- you do not have permission to install really useful extensions that put control in your hands.
Examples available on macos (so far) that are different:
* firefox + umatrix which give fine control of what is permitted/not at the browser level
* little snitch which can give fine-grained control of what network access applications can have (and the browser can be further restricted)
(I think little snitch might have a hole where dns lookups might still go through, unverified)
In that case, I'd still have to either audit the app's code or trust the author. With mobile Web, I know it won't spy on me like that because the browser won't let it.
+1. RedReader[1] is just awesome. In fact it's one of the few UIs I've used that I felt completely at home with from the first time I used it. It's filled to the brim with tools and options but I always find what I'm looking for.
