I'll admit, as an attorney, this isn't my specialty, and every jurisdiction varies, but the ye olde common law of tortuous interference requires something more than mere competition, this is America, not the EU.
2 DAN B. DOBBS, THE LAW OF TORTS §§ 448-52 (2001)("you are thus free to induce my customers, employees, or suppliers to deal with you instead of me, as long [as] they are not bound to me by contract").
Restatement (Second) of Torts § 768 (1979) (stating that interference with a competitor’s contractual relations is permissible if it does not employ wrongful means and is intended to advance the competing interest).
Wal-Mart Stores, Inc. v. Sturges, 52 S.W.3d 711, 726 (Tex. 2001) (" we conclude that to establish liability for interference with a prospective contractual or business relation the plaintiff must prove that it was harmed by the defendant's conduct that was either independently tortious or unlawful. By "independently tortious" we mean conduct that would violate some other recognized tort duty.").
