Ok, first off you just lost me here. I suddenly became so uninterested reading the rest. First you're saying that other OS keeps some sort of method to have an ongoing connection for the apps to use, and WP is the only OS that doesn't. Then you stated that basically in a "no-network" situation, mentioning WP8 in particular, makes all IM apps to render useless.
Now tell me, how can any OS, basically any device that is NOT connected to the network, can send or receive any messages and provide push notifications? Basically all these messaging apps need a data connection to send and receive data, no matter what the OS is.
And if you wanna use mobile data to have real time push notifications, you can set one of your emails "Download new content" to "as items arrive". That way any app can now have access to mobile network in real time. Also I have used Kik before, and it had real time notifications, without using the Music player stream like WhatsApp does. Skype calls and IMs goes through just fine, same with Viber.
Only WP8 by default allows that no-connection situation. Hence mentioned in particular. Other OSes do not allow that no network situation to occur.

Precisely, that is why Whatsapp uses the Audio API. Because all messaging apps need a data connection to send and receive data. All OSes allow this under all conditions, so Whatsapp there doesn't use a Audio API.
WP does not allow it under conditions of no data, screen off (by default). Bulk of Whatsapp userbase falls in this use case. Hence they NEED to use the Audio API to keep a connection alive.
It would have been clear had you bothered to read the first post which you admitted you din't. No point talking to you any further. Do you frequently call people haters without reading their post first?
