Oh, I am sure they'll try. The sales pitch is way too enticing for them to ignore. Imagine you're in a brick and mortar wireless store shopping for a new cell plan. A Meta user walks by, and you get caught in a frame. A facial recognition scan quickly links you to your shadow profile, and an image recognition model identifies that you are phone shopping. Meta knows who you are and pings your current carrier who quickly dispatches a phone call to you with a pre-emptive retention offer. It may sound outlandish, but all the pieces are there to do this today.
IMHO, we need strong regulation of facial recognition technology. The conversation too often focuses on law enforcement use - don't get me wrong, that is also important, but it completely ignores the risk posed by private databases.
More like when they decide to do that. They want to capture and extrapolate any and all data possible from every possible source.
