The advertising statements from Signal don’t help at all.
What they have published are responses to subpoena from US courts. Don’t believe courts would accept advertisements as response.
85% of the SP run on Google’s Android
So you are suggesting that android is the issue here? In that case it doesn’t matter which IM you are using, becoz as per this, android can send out a bunch of information about anything on your phone to google, in spite of what application you are using.
Android with google services could do this, probably is the reason why some people prefer to use de-googled android (one of the original question here that triggered this convo).
Google can assign the IPs to fixed users every day.
I certainly don’t get this. Google doesn’t assign IP addresses to your device. It’s done by your ISP.
Overall, to me it look like you are suggesting the devices running android itself is the problem. In that case, the only option is to do away with mobile phones, becoz, in spite of what OS you run, your service provider can track your exact physical location anytime, which could be more troubling.
And I get the argument that meta data is what gives you up and that is where an app that collects the least amount of meta data becomes more secure.
