I have no insights into the per-user cost for Meta to run their platform, but I have a hard time imagining that's what this is based on. I think it's much more likely that users are paying a price based on "what Meta could be making if they sold their data".

Pricing isn't based on operating costs but market value of services offered. That's how every business in the world works.

If Meta found a way to double their ad revenue from non-paying users, would you expect the price for this subscription to double?

Yes it'll actually have to more than double, since the high-value users (from perspective of advertisers) will more likely opt-in to the ad-free plan. The opportunity cost will be insane otherwise.
