I use free stuff on the internet all the time: YouTube, Wikipedia, Quora, Kahn, IXL, NASA, The Poetry Foundation, Britannica, thesaurus.com, wordgenius.com, dictionaries, school websites, and advice from writers, and more, and I download pdf's. No tutored students have to buy anything, with one exception: test prep books. If they cannot, I make copies (expensive). Almost every student is told not to use Wikipedia, and no explanations are given by anyone in the stuffy establishment.
The stench of arrogance in love with itself more than children/young adults is rising. He is an example of what schools turn out these days. When I saw the video, imagine the impolite words that came out of my mouth.
