So, thinking about this some more. A community and business have something in common: they probably have costs which need covering somehow. They can be covered through a system of monetary transactions (which can be structured in lots of different ways - membership fee, pay per item, discount for particular groups, etc), through contributions in kind, donations, etc.
They have another thing in common: they provide a service. The service can be provided to a restricted group of members (for example in a community) or through an open market (most businesses). The service can be better or lower quality, and can deliver differing experiences tailored to different needs and preferences.
So I think the underlying issue you’ve been driving at @William_Nichols, correct me if I’m wrong here, is the extent to which you prioritise merely covering your costs (and nothing more) and delivering a service tailored to the preferences of the community, vs making money and delivering a service which drives maximum sales. These are not completely mutually exclusive strategies, and they can be mutually supportive in the right circumstances. In the wrong circumstances they’ll compete and one will dominate the other. I say “circumstances”, that sounds like it’s down to luck, but clearly you can steer things in one direction or the other.
One thing I’d like to reiterate here is the value of labour. People giving their labour for free is a thing they can do, but it’s got all sorts of problems if used as the standard model in our current economic system. It advantages some people over others. It prevents most people from making the thing they love into their main gig. Even if only some people do it, it distorts the market and makes it harder for other people to earn money from their work. All of this is more apropos of the other thread but I think it bears mentioning here.
With all that in mind: I think navigating the space between “ruthlessly seek maximum profit” and “try to selflessly maximise community benefit” is a hugely subjective affair. It requires judgements to be made about both strategy but also fairness, and in many communities this means individuals are having to make that calculation blind, as in the your example where people are donating twenties. Because money does matter, if you adopt a wholly selfless model you can end up with something that’s unsustainable based on some people giving more than they can really afford in the long-term (whether that’s money or time). Equally, because goodwill matters, adopting a ruthless business model could mean you end up losing customers and therefore money.
My feeling is that most indie designers are working hard to reconcile the two. We’re trying to contribute and build community, in the belief that this is good for everyone, including our business. Many of us are also trying to make money, but also to spread it around among other creators.
So back to the point in the original thread, it’s not exactly a false dichotomy, but it also kind of is.
