Background
Rooting disables OEM updates and makes your device unofficial, so you will probably still be able to sideload apps. Depending on how this shitstorm turns out though, and if there will ever be a need for it, I would love to help people root their smartphones.
Another idea is to collaborate on a wiki that aggregates and documents all rootable versus non rootable smartphones and the methods that work.
Rooting services
We could setup a chatroom on Signal or any other platform that enables voice and/or video chat. People would also be able to send their smartphones to another person that roots it. Or like street vendors, setup a pipe chair and table and do it on scene at festivals and other gatherings.
The wiki
I could host something fresh from my desktop or create a community on some fedi instance. The wiki would aggregate preexisting information but also be open for continuous updates by the community.
Edit: thank you @ChanchoManco@lemmy.zip for posting the repo Bootloader Unlock: Wall of Shame
Question
What does the community think of such an idea? I'm just spitballing here, trying to add something to the opposition.
