Some people in this thread are comparing the situation to that of news site paywalls and noting the recent change in google image search. I think there is something to the comparison and it highlights the fundamentally different opinions about the purpose of a search engine:
Users want a search engine to find information they are looking for.
Businesses and sites want a search engine to advertise which information they could provide - but not lead directly to the pieces of information in question.
I think it's worth to make this divide visible and start a discussion which kind of search engine we'd like to have.
