Yes, 'universal within the defined scope'. Everything within that service.

Microsoft Windows doesn't have a backdoor to data on your android phone, but its backdoor is still universal within the scope of your your Windows installation'. Do you have a more appropriate term he could've used? I'm not familiar with one offhand, if you know one I'd appreciate you sharing it.

How about just "backdoor" then. "Within a defined scope" != "applicable to all cases" which is the definition of universal. Precise, honest wording is important.
