I think they mentioned this on the WAN show were we had an unusual length of time where things were stable. We used to pick up and drop websites all the time. Facebook, Twitter and Reddit's dominance was great stability in a time when things were constantly changing.
I emphasize with the writers viewpoint of a space where everyone is on, but all three have been shown to be run by what seems to be people with dubious judgement (putting it lightly).
I think these changes are long overdue.
