Social network movie problem

I've seen it a dozen times. Let me talk about my personal understanding:

I don't think Mark framed the chicken. His feelings for Eduardo have not yet broken down. Later, when Eduardo mentioned the chicken in court, Mark was very dismissive. He may think that Eduardo is involved in such unnecessary and naive things.

Sean is selfish. To some extent, he realized his ambition with the help of Mark. On the other hand, he was unprepared for Mark. He thought Mark was a skilled house, but he didn't expect Mark to turn it upside down in the end.

From the beginning, Eduardo had an affair with Mark on the website. Mark thinks that many of Eduardo's ideas will make the website cliche, but Sean has foresight. He hit it off with Mark and Eduardo was alienated. In a rage, he made a move to freeze funds, which can be said to be the fuse for the two to break up.

Abandoning friendship and cruelly ignoring friends for the sake of career is Mark's fate, but he doesn't know what happened. He is just a genius with social obstacles.
