Oh, most definitely they are not my search engine either (and I am not talking about any absolute right or wrong, just what I consider better).
It's just that it shouldn't be presented different content than what I can see browsing to the page myself: if both Google and me can only see abstracts, that's fine to me too.
If not, I am happy to use paywall-avoiding sites so publishers would reduce power Google has over them sooner.
Basically, it is my initiative to drive behaviour that I want in the market: either offer content for free, or restrict commercial search engines too.
