Critics of libertarians often conflate capitalism with a handful of specific business models (like fee-for-service or ad-supported). This leads many of those critics to falsely conclude that anytime a libertarian supports an enterprise that strays from the bounds of these business models, that libertarian is engaging in behavior that is incompatible with "capitalism" and is therefore being hypocritical.
In reality, such a charge reflects the ignorance of the accuser. Libertarians support capitalism not because of how awesome money is, but rather because it is consistent with the general notion that individuals ought to be free to engage in consensual transactions with other individuals, regardless of whether such transactions are profitable or even involve money at all.
