I don't care if anyone has a Xiaomi, Oneplus, Samsung, etc. Each brand is using a modified version of Android, and they chose to be compatible with each other. But for example the "blue vs green bubble" drama is a thing specifically because of Apple locking their unsuspecting users into a closed ecosystem. And it sure isn't Android's fault for not being compatible with it.
The more power a company like this gains, the worse will it be for the whole industry.
You’re talking about data stored in the apple cloud (I think without the account recovery turned off, but I’m not 100% on that). The same is true of googles cloud services.
Agencies haven’t been focusing on getting the actual texts that say “here I go, doing something you don’t like!” For quite a while because of the amount of variability involved. What I hear spooks talking about is building enough pc for a rubber hose interrogation with unsecured parallel data streams like push notifications.
