Barnes and Frey didn't read the contract closely.

Uncivil Law is a friend of theirs and he goes over the contract here: https://www.youtube.com/watch?v=PhWDKx9myI0&t=6187s

He's a conservative lawyer, so he doesn't have a political bias against Parler. They just don't have a case. I think Parler's lawyers misread the contract and thought the 30-day notice applied to termination for cause.
