Take the package and go to find the new job.
This is a typical american style "lay-off". Usually the company had a plan to cut the manpower. With the package, this kind of layoff will not increase the company insurance premium in the next few years and most likelu has no risk of lawsue for discrimination. As for "communication" and "meet expectation", all are excuse.
Take the package or even try to ask a little more.
