this was last year's story, Sooyeon posted on SNS why she couldn't attend their fan meeting. The articles were already out and SM was trying to restrict her schedules so that's why Sooyeon couldn't attend her fan meeting in the end. And when Sooyeon brought this up, she said that it was only one party's decision and that SM was lying but she was forced to accept it. If it was for her own good, why would she self-handicap? The decision was made uniquely bu the 8 members and they decided to kick her out and not let her in the company to decide with them.
