I read the timeline and also came out with a negative impression of Blake Lively.
She forced her way into taking over the movie. She was a lead actress, not a producer. She insisted on a substantial level of control to the point where the studio themselves were emailing JB concerned about the level of infuence she was having. As a result of her interference, she ended up with a producer credit. The emails have confirmed all of this.
She admitted to stealing the edit and showcasing it publicly without approval to get test audiences to prefer her version. This is something she's admitted on film - not within the legal filings.
She also admitted on the red carpet that RR rewrote certain scenes without the studio knowing. The legal filings showed the studio shat themselves at that point because they needed certain authoritisation for that. This also needs to be pointed out that these "rewrites" were taking place during the SAG-AFTRA strike (of which RR and BL are members) - so she pretty much outed them both as scabs.
There is also significant heresay going on.
Allegedly she wanted JB to sell her the rights to the sequel but apparantly he refused. There was a rumour (unsubstantiated) that Colleen Hoover had a morality clause in the contract for the rights to option her books - therefore, there's a theory that BL orchestrated this whole movement so that JB was falling foul of that morality clause, hence Colleen Hoover could regain the rights to the sequal and give them to BL. I have absolutely no idea if this is true or not.
I also have no idea about the sexual harrassment relevations so I won't comment on those. But I do genuinely think she's shown herself and her husband to be difficult to work with, and I think that she's sabotaged her own career
