I think that those who are most passionate about this situation, and are sticking to their morals, tend to be are more active group and the power users who are actually the backbone of reddit. On reddit, I post a lot, I comment and discuss a lot, and I participate in a ton of communities. I offer a lot of expertise in the niches I am in. I am not going back without a 3rd party app compromise. I think many like me feel the same way. Those who just consume on reddit will probably return.
I am a fan of blue bubbles :)
