Search engines that obey robots.txt are stealing?

If someone does not want on a search engine index and they say not to index, and then get indexed anyhow is stealing.

But a “please read my content and make available to your users” then claim doing so is stealing seems a bit out there.

What am I missing?

There is a difference between "read my content and make it available to your users" and "make money by reading my content and making it available to your users". Terms of use like this are trying to say "we are the only ones who get to make money from this", and therein lies the problem.
