Doing CAPs to manage people out and avoid paying severance has been happening a lot for at least a couple of years.
We are hearing about it more because it works and they are doing it more. The company saves money by pushing out long-term, expensive employees, especially those seen as too vocal, ethical, or outside the in-crowd.
Expect more of this. Most people do not have the money, time, or stability to fight it legally, and many assume it cannot happen to them until it does.
