World is a big place and in some areas (like mine) all the services you mentioned aren't popular at all. I doubt 1% of communication happens through them. People around use gtalk and facebook messanger. They used to use GG (Polish product, some time ago most popular here) and Skype but most of them switched to either gtalk or fb. Maybe you don't see complaining because services you mentioned didn't come about as replacement for traditional chat clients integrating most important features of those only to get rid of all this in one go once the user base switched.
