I wonder how Google will react if more and more mobile phones with GrapheneOS appear on the market. I suspect they will block further adoption by throwing up all kinds of hurdles. They could make more parts of Android closed source, even critical ones without which you cannot realistically build an Android phone. It could, however, trigger anti-trust lawsuits, but my guess is they're willing to risk that. I mean, worst-case they only have to rollback to what they already had and maybe pay a fine.
