It's always nice to read Corey eating at the buffet of corporate shenanigans and leaving no crumbs.
If this developer registration really comes to pass and/or has staying power, I suspect there will be eff it we will just fork it movement. A FOSS Tyzen or Fire version of Android that would then not go back to whatever Google does with their Android updates. That would probably work better if all the privacy-friendly Android devs banded together, which probably won't happen.
At the same time, I don't think the last word has been spoken on Google's plans here. They haven't implemented it yet. And even if/when they do, I suspect there will one or two courtrooms that will hear about this shit in excruciating detail. If European devs could rally behind this flag there is a good chance the EU will use its golden formula of 50% good intentions and 50% wanting to eff American tech giants to intervene on privacy grounds.
