Video lecture question

Hey Greg! ,
Hope this finds you well!

I have a question regarding the Main idea of this passage (screenshot)

So for the main idea , I wrote something like this:

“FM ranked below SB despite genius acknowledgement”

Can you please explain why is this incorrect and where I went wrong? (I actually came here after watching the video session)

Also , is the author’s opinion always the main idea of the passage?

Looking forward to hear from you soon
Thanks in advance
