What I feel no one is asking is, and what I'm still confused about, would MicroG still be working wthin all of this? Its a sandbox, I get it, but that dosent mean it could have the ability to stop working since it can't access apps. Like if that gets closed off, then what? There are still some app that are not fully stock android that a lot of people need to use unless you have them on computer or tablet ( For banking for example, I use my apps for all my finances on my iPad)
Maybe I don't get how the sandboxing works for MicroG but, if its using google, I would avoid it as much as I can.
