The cynical answer is because once you install an app they can * Push ads to you even when you're not viewing their content * Read your address book I hate it

The cynical answer is because once you install an app they can * Push ads to you even when you're not viewing their content * Read your address book I hate it too. I also hate sites that ask me to install their app every time I visit. No, I don't want the IMDB app nor do I want the Rottentomatoes app, etc etc.. Unfortunately the majority seem to love it :-(
