I respect CTO for standing up for what she believed in (even though we may have disagreed with her stance, we must remember that everybody has an opinion). But we always remember that once something is posted and it's out in the public, it's out there forever.
I'm extremely careful with social media now. Back when I was in college, I had received an internship offer from an NFL that I accepted. Another team offered me a position as well, but I had posted something on Twitter before letting this second NFL team know I had taken another offer. When I reached out to that team telling them I declined their offer, the hiring manager replied back saying they saw my Tweet a few days prior and hired another candidate and hoped that my next decision I would handle more professionally. Since then, I ALWAYS watch what I say because I know people are watching.
