I think it’s pretty obvious at this point that what Zuckerberg done was immoral. They lost something like $72 billion in two days. That is already a decent message to future generations. Or maybe it’s not enough. I doubt that if the company starts doing badly financially, that others will not buy it. They probably will and then they’ll continue letting others use it for being able to get around.
I do find the fact that they programmed Facebook to be addictive somewhat troubling. It is important to stress however that most services we use are like that and take advantage of our human nature.
It seems to be our responsibility to go against these addictions of ours.
