Suppose party A has contractual obligations to party B for maintaining confidentiality, and party A obtains equipment or services from party C, a vendor who is aware that their customers in general have such confidentiality obligations, and/or specifically that customer A does.
Now party C goes and makes alterations to the equipment or service in ways that cause it to surreptitiously record information passing through it in ways that prevent party A from honoring their confidentiality obligation to party B.
Does party A have a cause of action against party C (as tortious interference or otherwise) for doing this?
