Just sue them under monopoly laws.
Under Title II Google should be allowed access, regardless of ownership and negotiations. Being a cable company, defined as a cable provider or anything of that sort should be playing no role.
Google should be using the Title II classification since it's also an internet provider. Seeing as internet providers, formerly an information service, have been re-classified as utilities Google should have open access. The "cable TV" package should be secondary to the IP service portion of the sold packages.
Again, just sue them all under monopoly law and Title II.
