It does. There's no free market for soup kitchens for the homeless, for example.

There exist entities who are willing to provide soup kitchen services below operating costs in perpetuity (i.e. charitably, for free). The price for services is kept artificially low ($0) by constant infusions of capital from outside the market (charitable donations), which prevents for-profit vendors who don't receive constant cash infusions from being able to compete on a level playing field. The resulting market is thereby warped by the distorting influence from non-market forces, preventing it from operating efficiently. It's not "free", in the technical sense.

This isn't necessarily a bad thing, to be clear. The charitable funding system may well provide better aggregate social outcomes than a free market would for any number of reasons, not the least of which being that one of the freedoms that "free market" implies is the freedom for vendors to decide that some of their potential customers are more trouble than they're worth to serve.

You illustrate the point well and maybe I'm just not well versed enough in the topic. You imply that a charity warps the free market by undercutting profit-motivated competitors but in the last statement you give the vendors the freedom of choice in regards to their customers. Is there any reason why this same freedom of choice can't be extended to people who choose a specific social outcome at the cost of less (or nil) profit? For example, are B-Corps fundamentally less "free market"? Or does the very nature of free market imply a profit maximizing function? As an example that comes to mind, I'm curious how not-for-profit and for-profit hospitals interact in a "free market" of healthcare in the United States.
