Ms. Sheryl Sandberg at the meeting
It should be noted that Sandberg does not show any remorse about the study, nor does it mention that Facebook will improve communication, conveying to users in the future. Basically, this is not an apology, and Facebook only regretted that users were upset about the company's actions.
Moreover, one of the purposes of this study is designed to make people feel uncomfortable, or at least to see if Facebook can do it. According to Sandberg , Facebook often does this. The results of the experiment show that Facebook has a very good ability to shape people's moods through algorithms. This is a very frightening thought and it is not easy to be appeased by a half-hearted apology.
