I know I'll stay in Tumblr for sure. I was never there for the good erotic / pornographic content anyway, I just found it a good bonus. I found a number of very good creators of pixel art which is a personal favourite, and a ton of good home design blogs. I love all these and I'll keep following them in Tumblr.

However, now it's very likely that I'll find a mediating app -- or I'll be scraping my own feed -- to avoid the inevitable increased influx of advertisements so Verizon will still lose that possible income from me. I suspect many others will take similar measures (less known apps like Tyblr in iOS for example rid you of ads and make your feed sorted by timestamp and not by an "algorithm").
