Are you saying that there's no excerpt at all above the search results, when you expected one; or that there is an excerpt, but it's not from the most appropriate/relevant source?
It's annoying when there's a page that has all the information you might need, but to find it, you first have to scroll past a bunch of Stack Overflow posts that are more suitable for dilettantes who prioritise trying a quick fix over learning best practices. But when you do make the effort to find the most promising link and your browser allows the search engine to record your choice, you at least get a vote regarding how the ranking should be adjusted. When users just look at the results but don't interact with them any further, that feedback vanishes.
A win for Google isn't necessarily a win for Google users.
I do emphathize with the companies being scooped by Google, and so I have concern that they are viable economically and that Google compensates them for getting the info from them.
But in the mean time, it's a success for me when my search gives me the answer immediately instead of two or three rounds of indirection.
