That’s why I am a fan of crowdfunding with utility tokens.
People on HN have to realize there is more to capitalism than shareholder capitalism and extracting rents from ecosystems ;-)
This can work, but definitely not through crowdfunding. This better works through say business associations, say a national taxi association (composed of all small/regional taxi operators). That association can allocate a small portion of the funds to build this open taxi framework.
There's good margins in any software that people want to use. There's money in Nextcloud hosting, Matomo services, or Bitcoin. All of which are open source projects that attempt(or attempted to) put power back in hands of users. There are many more examples.
VC will gladly fund a business model with solid margins. They often prefer those that might get a monopoly, grow exponential etc. sure. But it's certainly not the only mode.
