She's not technically right. Her article is filled with "all my bosses cheerfully agreed that the social media policy was impossible to comply with", which is nonsense. She could have just stopped using Twitter. She's not a shark who will die if she doesn't tweet every few minutes, it's just social media. Yet she seems to be convinced that she found some clever gotcha here and everyone in every meeting bowed to her superior intellect, meaning she has an impressive inability to read her colleagues.
