It will be us webmasters.

Except the webmasters still doing well in Google won't want to buck the system because it will cause them short term loses as they ignore the long term gains.

The only webmasters willing to take action will already be harmed and taking action, such as blocking their crawlers, will have no impact, it will just be a symbolic gesture.
