The Office's Rainn Wilson expressed support for Baldoni in texts, praising him for not apologizing quickly and encouraging him to do a story about the whole thing. I personally feel sorry for Baldoni because Lively and Reynolds are Hollywood's darlings and he just didn't stand a chance in this battle.
Also, being sidelined from the premiere of your own film while someone else uses it to market themselves and make money is so hurtful. Now, I don't know the extent of Baldoni's involvement in Lively's alleged harrassment, but I think Lively and Reynolds totally milked the fallout for all it was worth.
