Bandcamp didn’t build goodwill without spending money. In fact, it gained goodwill precisely because it spent its money in ways consistent with building goodwill.
Slow to produce, quick to consume.
That bias tends to mean that large corporations consume more than they produce over time, as they’re biased towards short term financial results — but you absolutely can grow goodwill with money plus time.
Look at esports, where years of financing community contests have earned good will from players.
Or the numerous charities that corporations like McDonalds run. Ronald McDonald house can and does earn them a lot of good will — which they turn around and spend on short term results.
My point is this is less about entropy than the short-term managerial culture we follow.
So in the real world, (real) goodwill turns into more money. But in accounting, money turns into goodwill!
"In accounting, goodwill is an intangible asset recognized when a firm is purchased as a going concern. It reflects the premium that the buyer pays in addition to the net value of its other assets. Goodwill is often understood to represent the firm's intrinsic ability to acquire and retain customer business, where that ability is not otherwise attributable to brand name recognition, contractual arrangements or other specific factors" (Wikipedia)
(Can you think of an counterexample? A small, beloved indie business that was bought out by a megacorp and had consumers love it more because it had more money?)
So, it's like entropy. The latch only moves in one direction. Given a consumer beloved business, the only possible thing that can happen is that its goodwill is turned, quickly or slowly, into money. This is actually ok. Every beautiful living thing will eventually die. It's simply a fact of life. Cherish the good things while you can, because entropy will always win.
