Social media is an excellent tool for publicly shaming companies
I don't think we should seek to become a society running on public shame. Didn't we used to identify that kind of society with "The Crucible" and "The Scarlet Letter?"
"How did you know about that? A little bird told me."
Also sadly, some of those same companies seem to be enabling this shaming culture. (Twitter banning random users for just using the LearnToCode hashtag, while not banning journalists who called for the doxxing and harassment of a minor. Also: https://www.youtube.com/watch?v=wAIP6fI0NAI )
