With all the turmoil at Twitter, companies and celebrities are posting their final tweets, some giving reasons and some quietly slipping away. Their choices offer lessons in integrity and authenticity. Here are examples for students to analyze:

CBS News Bay Area: In light of the uncertainty around Twitter and out of an abundance of caution, CBS News Bay Area is pausing its activity on the social media site as we continue to monitor the platform.

Playbill: [at right]

Balenciaga: [Deleted account without comment.]

Shonda Rhimes: Not hanging around for whatever Elon has planned. Bye.

Sara Bareilles: Welp. It’s been fun Twitter. I’m out. See you on other platforms, peeps. Sorry, this one’s just not for me. [heart and prayer-hands emojis]

Toni Braxton: I'm shocked and appalled at some of the "free speech" I've seen on this platform since its acquisition. Hate speech under the veil of "free speech" is unacceptable; therefore I am choosing to stay off Twitter as it is no longer a safe space for myself, my sons and other POC.
