Those exist everywhere in the trades. Every major city has dozens of small businesses doing plumbing, electrical, roofs, etc., with the goal of sustainable, loyal customers based on doing a good job at a fair price.
The real value is probably in new product models that can only exist given an ethical perspective. Perhaps reviving the mostly dead pay once use forever model of software would work well.
That model requires abandoning DRM which the unethical companies will never do.
The main difference in the software world is that you can potentially build things "once" (or rather, keep building it forever) for a huge global market, which means that it's hard to know when something is good enough. With roofing or coffee, you do good enough work (differs between companies, sure) and move on to the next customer.
But you don't think about adding continuously running rainfall test for the roofs you do to ensure no regressions (leaks) appear.
