Nope, making a paywall not show content to Google bots is a (slow) way to get us out of our misery.

Basically, as long as search traffic is more important to publishers, Google will have an upper hand.

If paywalls are in our future, getting there through Google should not be.

By working around paywalls, you are asking publishers to not mess the search results or not to give Google preferential treatment (depending on your angle).

Exactly this, the "why?" section sounded weird to me. Paywalls (specifically subscriptions and paying for a service directly) are a way to not need AdWords, if those don't work then what can websites do to make back their hosting, dev, writing and all other costs than using Ads
