Well, I would hope that purchase of a product or service is a mutually beneficial business transaction. So in this sense how the product is priced is the problem/concern of both parties.

Quoting from https://museapp.com/memos/2021-06-pricing/ :

> You might be used to software from growth-at-all-costs startups: free at the start (funded by venture capital) but eventually your attention in monetized with ads, your personal data is monetized by selling to third parties, or the personal product takes a back seat to the “enterprise” product.

> Muse is following a different path: personal software, made for you and your unique tastes and needs, and funded by direct payment from you and other members. Because our funding comes from you, the customer, rather than investors with their sights on mass-market adoption, our incentives are better aligned with yours.

> By paying for Muse, you help us stay niche, opinionated, and focused on your needs over the long term.

I think it's worth thinking about where the products and services we consume in our daily lives come from and how the incentive models work. And that definitely includes software.
