I assume you are extending the analogy by implying that one "warehouse" would be paying users, and the other "warehouse" is free to use / advertising / giving up private data users.

This analogy falls flat, because unlike an alcoholic which can be satiated at some point, FAANG can never be satiated. More information is always good. Thus taking data from both warehouses is better than restricting yourself to only one.

Secondly it also falls flat because your paying users is often the more juicy targets (from an advertising point of view), since they are already well enough off to pay for ad-free internet services, thus also well enough off to target for more lucrative advertising.

Getting back to the analogy, it is like an alcoholic guards two warehouses, one stocked with free budweiser beer, and the other stocked with the finest scotch, and hoping he wont take a swig from the scotch.
