I find the cosmic firecracker model to be a little incomplete.

If motions in different reference frames can be equivalent, then
cosmic expansion is equivalent to local contraction. You cannot
conclude from redshift that we neccesarily have expansion.

If we were contracting locally you would have the same redshift.

These things are equivalent.
