I've been running open source, free, libre, etc software since the mid-90s. My firewall is openbsd. my laptop runs linux. I use emacs for most of my software editing. I want you to understand that I am a big open source weenie, and have been for decades.

I think asking consumers to evaluate risk of installing third party apps and manage permissions is insane. My phone runs iOS. My family the same. The volume of malware in the Play Store alone, much less in the sideloading community is mind boggling. If I ran Android I would only install software that I had written myself or come from a trusted vendor, and only use a browser (probably not Chrome even, but Firefox) for any third party content.

Any anti-walled-garden screed has to grapple with the fact that in the real world, the walled garden protects people from mass data theft and infiltration. Windows used to be like this, before many more users switched to Mac (which is harder, but not impossible) to backdoor. Replicating the internet security environment of the late 90s but on our phones would be a disaster for the technology-using world.
