Just because you made the mistake buying into a shitty walled garden like iOS doesn’t mean it doesn’t work for other people.

So much misfires in one single sentence. Impressive.

• "you made the mistake": I am not talking my phone, but from other people that I want to talk to.
• "shitty walled garden like iOS": I may not like, and you may not like, but there are 20-30% of the whole world that to do prefer to have a phone that gives them a walled garden and gives them some peace of mind. But instead of accepting that other might have different values than you, you try to dismiss their values as secondary to your cause and you pass your values as something that should be universal. Are you noticing the pattern here?
• doesn’t mean it doesn’t work for other people: if someone on Android can not have video calls via XMPP with someone on iOS, then no, it doesn't work for neither of them.

I see a pattern here of you ignoring reality

You want to keep believing that your solution is superior and that the problem is with everyone else that keeps choosing the wrong things? Fine, I will not be able to convince you otherwise. But to keep being presented with actual experience from other people and respond by saying that "they are ignoring reality"? This is just silly.
