Personally I think people are overreacting. As far as I know you can turn everything off in the settings. People also complained about the privacy-preserving measurement being on by default but I’m pretty sure that was a bug because on a new install it gets disabled when you disable Firefox studies and other collection stuff.

I do have an old phone that I plan to try this with it’s just that it’ll be at least a week before I get the phone in my hands as I don’t have it with me where I’m at. Also I’ll have to work on hiding the fact that it’s rooted since the BookWalker app won’t run if it is. I’m just trying to make my life easier, that’s all 😅

Unless I’m missing something deDRM does not support BookWalker
