The whole idea behind these apps is in gaining access to user's data. This is why in recent versions of Android user cannot control not just what an app could do, but whether or not it should be started automatically. The "strategy" is very straightforward - first to gain "popularity" offering a reasonable service "for free" and then, after accumulation what they call "user base" they just change the rules (permissions). The idea behind separate "messenger" app is exactly to "hijack" user's messaging service by "forcing itself to be" default messaging app. I don't even want to talk what kind of spyware Skype is, using exactly the same "strategy" of quietly "adding functionality" and having permissions to do everything. There is no other "working" way to monetize user's data, but collecting and selling it. The next level is just adding malware functions in "next version".)
