Just to be charitable - I can imagine Workflow enter discussions to be acquired and get told that they need to make sure that they have permission to link to those other apps by Apple Legal before anything can happen.
Being a small dev team, and not a corporation with a giant legal department, they panic at the amount of permissions they need to acquire (Workflow deals with a lot of apps) and rush through it as quickly as possible. Coupled with the fact that they, unlike Apple, are a tiny company that doesn't actually make much money off the app, so don't want to end up entering long-standing commercial agreements when the deal may still fall through.
Apple then insists that anything that they haven't had a formal agreement to on a particular date is removed from the app if they want the acquisition to proceed.
Whether that means that they now contact Google again is another question entirely (personally, given that the point of Workflow is to link as many apps together as possible I would hope so)
