I mean, with a company as large as cloudflare. I think they could /easily/ strong-arm this move by making blocking google crawlers a default setting on websites. The amount of traffic drop alone from that would make google think twice about the whole ordeal. And people who care about the google search indexers can turn them on again which will allow indexing again. but a default block would cause a lot of disruption google side and many people I don't think would go in and fix the setting till later on down the road.
