I’m a hardliner when it comes to user control of their own devices, so I’m not going to agree with Google’s behavior here even if it, on average results in a benefit to users.

I don’t think it provides a net benefit to users though. I think Google wants to be lazy about building spam-mitigation solutions, and wouldn’t be sad if it results in fewer users blocking ads and tracking. If Google was positioning its RCS client as a hardcore security product, maybe it should warn both sides of the conversations that there’s a risk of compromise, but even Signal, which is far more dedicated to security doesn’t do that.

Zero-click exploits are a more common attack vector than modified operating systems in the real world, and I’d be willing to wager my up-to-date LineageOS install is less vulnerable to them than the average person’s phone.
