The true problem is rarely the technology. The problem is the people who use and abuse the technology.
Will we see Steemit succumb to the wills of humans? Of course we will. In fact it's already here.
But just like any society there are those who choose to live on the fringes of society. There's a lot of us who simply ignore the technologies listed above (well, except for Netflix, that's different ;-). We chose to focus on those things that build relationships with other humans, not those things that create drama, strife, discord, or greed.
It's like living in a big city. There are many unmentionable things that abound in a city but there are also parks with the occasional flower or squirrel. We simply learn to find the parks in the midst of the city.
You also learn which streets to avoid and when.
I agree with you @yulem. It's people who are in charge of taking these "sins" into the apps. That's why FB and Instagram are trying to come back to the main target of creating social interaction by eliminating what is not useful in this network. And yeah, I'm also focused on talking with people face to face, calling them, going for a walk and other activities that help to keep the human contact.
