Without search engines how would you find that content?

[fantomsurfer]

I don't say that they are useless. Point is that they are crawling the content, wasting bandwidth without paying for it.

The engines make the big money, not the webmasters.

I think the issue is not so much that they exist, the issue is that they profit greatly from content created by others without paying said others a single penny.
