Can You Use Khan Academy in Iran?

Hello, thank you for taking the time to read this post. I am an Iranian who has been using Khan Academy for a while. I have to say that it is probably the best learning site that I know of, and I love it! But of course, any US-based company must comply with applicable laws and sanctions. In the Terms of Service, I saw a paragraph prohibiting use of the Services in U.S. embargoed countries. That was clear. But the main points of confusion for me are that: 1. The website still gives me access and doesn't block me, even though I am accessing the Services without any workarounds. 2. I saw in a Khan Academy Support page that people in China and Iran are able to access the services and that the site "should function correctly." 3. In General License D-2 legislated by OFAC, it is authorized to provide Iranians with services incident to e-learning (Khan Academy is an e-learning platform.) These appear to contradict what the TOS allows. May I be provided guidance? Thanks.
