The problem with paywalled news articles is that the ranking is done on the full article content, yet I am not allowed to see it. This often outranks the results I am allowed to see. Product pages don't have this problem.
Paywalled news articles rank on their full content (potentially displacing other, free sources) yet do not allow me to see it without paying. That's a bit of a problem because if I don't intend or am unable to pay I would much prefer seeing the other source which is free.
(the ice cream example is disingenuous because clearly we do not yet have the technology for ice-cream-over-HTTP. And when we do get such technology, then absolutely give me the option to block paywalled ice cream).
