Just to give an idea of how crazy it is here is a list of the synopsys TSMC 7nm cell libraries [1] and of course their are other companies that offer additional cell libraries. Also I have no way of proving this, but I wouldn't be at all surprised if both AMD and Apple have their own customizations or additions to whatever cell library they use.
