Ah, the old "we can't stop everything so why bother trying" attack. (There's a better name for it but I cannot remember it) But a few points: - No company has unlimited resources. The universe doesn't have unlimited resources, AFAWK. - Even quantum computers can only take the square root of the complexity of many algorithms (Shor's algorithm). - Even if a company can, with concentrated effort, break the encryption used, it prevents (or at least drastically limits) mass surveillance. (If it costs your company a cent to decrypt a transmission, you'll decrypt a whole lot more than if it costs a million dollars per.)
