why is are so many of the best authors leaving

this week we received blogs that alys was leaving and then michelle. Now i read angel is upset and leaving. There is just so much bad news that it has made me feel so sad. I loved all of their stories. Angels was wonderful she is such a talented author i really don't want her to leave. :((
I tried to send her a encouraging PM but i guess she is so upset she turned them off. What is going on with big closet lately
