They are difficult to explain, but the result is that the optimizer make quicker and better choices in how to execute queries, resulting in improved performance. The close relationship between our developers and users reporting problems allows us to make rapid and complex optimizer improvements that would be very difficult for lose-source companies to emulate.

Hey, that's your content-free fluff.  :-)

You make major optimizer improvements in every release, but they are so
complex it is impossible to explain them to people.  This paragraph
tries to address that.

However, since you don't like it, I will remove it entirely.  If you
change your mind we can re-add it.
