&gt;  Sets up a monopoly, vendor-lock-in, changes habits: Facebook would hold immeasurable power, once they&#x27;ve got people hooked onto thinking that there&#x27;s nothing beyond their apps. &lt;<p>I wanna deal with this monopoly argument I keep hearing everywhere in this thread.<p>Can there be a monopoly of a web service? Facebook dethrowned MySpace, did myspace have a monopoly? MySpace dethrowned Friendster.<p>If Google has a monopoly in Search and email then what use is it when it can&#x27;t push Google Plus? Even with Youtube integration FORCED upon people, nobody used Google plus.<p>Pretty much every single product other than social networks which Facebook has launched, has been a failure.  It couldn&#x27;t replace Gmail, Snapchat, Instagram.<p>Microsoft couldn&#x27;t compete with iPod, Apple couldn&#x27;t compete on Maps.<p>It just doesn&#x27;t matter how much is your market share in a certain existing technology, people judge things based on the products (considering there is no &#x27;price&#x27; to lure people away with).
