Tumblr (like lot's of platforms) has trouble sorting between "sure, no problem" and "hey, wait a minute" content - for them it's child pornography that needs a ban. Today's difficulties in policing content when the stakes are this high are proving too much for them and they're finding it easier to just burn all the way to the edges. If they take a hit for doing that they take a hit and so be it.
I think what will be very interesting to see is going to be what happens if the fire continues unabated, and other (larger) platforms fail to police their content as well. What if Facebook can't keep out the next Cambridge Analytica, or Google can't identify terrorist videos quickly enough for its advertisers?
Social media, because we spend so much time on it, is especially vulnerable but anything we devote chunks of our day too is prone to potentially coming down if we don't learn to seperate the wheat from the chaff. Either we get better at fighting off ne'er-do-wells, or we'll need to sort out new models entirely - ones that aren't quite so easy to abuse. Which way will things go in the end?
