The Facebook dislike button

In recent days, my Facebook wall was full with messages that a new dislike button is available and that I should try it out. I would like to give a short comment on this. First of all, I must say that those who got trapped by this spam didn't understand anything about the underlying principles of social platforms.
A dislike button will never be implemented by Facebook, as social relationships need an ecosystem that is built on positivity. A dislike button goes against all of that and would only promote negativity. Imagine the situation, where a friend is sick, missed an exam, is late or angry. What would be the meaning of a dislike for such a status message? Well, nothing. Instead, there is the possibility to comment and express your sympathy. A dislike without explanation is completely meaningless. However, this is not the case for a like, as it creates an implicit social proximity between you and your friend. More concretely, no explanation is needed.
There is also a different dimension for the fact, that social media sites try to build ecosystems that are based on positivity. Yes, you guessed it. Revenue.
Revenue goes beyond the desire of social media sites to connect people in a positive fashion. Company pages and sponsored ads build up the revenue for Facebook. Now, if half a billion of people would dislike such ads, that cost a company a huge amount of money to promote, what would be the business for Facebook?
So, my dear friends, first think before being trapped by dislike buttons and spams that claim, they will tell you who viewed your profile. None of them will ever exist. For the second, I will let you guess why. Put it in a comment.
