That sounds rather like "we can use this media because we're talking about clever stuff but people talking about trivial stuff clearly shouldn't use it".
That said, maybe the differences comes down to: are we being drawn in through manipulation to post beyond what we otherwise would have wanted to, for the benefit of others? To an extent, this is what karma is.
Now, who's fault is it for being drawn in more than I want to be? I take responsibility for it and also agnolage my weaknesses for distraction. Maybe you could equate social media to a liquor store. Fulfilling a demand, serving the community, and also praying on and enabling it, in a bad way.
Most of the time I'm distracted by social media, I would be better served by sleeping.
