Iris being hella salty, and rightly so, about the fact that literally everyone in her life knew Barry was the Flash before her...

And she’s totally right that knowing about Barry is better that being kept in the dark. She would know what dangers to be prepared for/what’s out there, what to write in her blog, and maybe even be able to use her journalism access/knowledge to help them research info, in order to catch metahumans. Plus, it’s also crazy rude that Barry would keep a secret that big from Iris, his supposed best friend.
