I highly admire the approach of prof. Dijkstra here, since the purpose of going to University is to learn the most we can, from people who know the stuff they're teaching very well, or have the ability to understand said things at a deeper level than the student currently has.
Thus, I cannot see how paying tuition entitles us to demand a professor to do X/Y/Z for us, we're paying not for them to be at our feet, but for access to their understanding of subject matter, which often (depending on the prof./University) is world class.
I also do not see how the professor comes across as omnipotent here at all, he gives students complete control, as can be seen in If I use a word you don't recognize or a sentence you cannot attach a meaning to, it is your duty to ask for clarification. If I go too fast, it is your duty to slow me down.
We pay for our professor's time, and very often the professors who treat the students as adults are the most effective, and are contributing not just to the knowledge of the student, but to their growth as independent thinkers as well.
