By far windows, windows lacks or doesn't fully utilize features like full verified boot, sandboxing which means even if a program installs itself it still has to ask for permission for mic, camera, etc. Adding on to the issues even the programs themselves can be unsafe. Running a program that uses a memory safe programming language is pretty rare and a lot of vulnerabilities come from memory allocation and buffer overflow bugs. Android attempts to mitigate these issues by sandboxing every app, all phones ship with verified boot and full disk encryption, and usually have a memory allocator of sorts. And if you run a degoogled ROM you'll mitigate the privacy issues by not having Google play services installed.
If you need some way to monitor these devices as an admin there are apps on android that allow this functionality, iOS has similar admin features.
Pertaining to the signal issue, as with anything, if you and I can use it, so can corrupt politicians, drug dealers, terrorists, and more. Signal is a great tool but it can be abused like anything else
edit: I'm not saying what these politicians are doing is okay, I'm only mentioning this just in case someone is anti-encryption, encryption is good and any political figure trying to outlaw it can go fuck themselves
Okay great, if I live anywhere besides NYC, where's my damn train for transport? Oh right its nonexistent. I'd love to take a train but the people that run this shithole say its too expensive and continue to pave more roads! Wow I love living here where my government continues to listen to big oil and destroy the planet in the process!!
HELLO?? Am I in some kind of weird fever dream? Can the people running the matrix simulation tap the breaks so I can actually assess one platform burning at a time please?
