You can't because the digital landlords make everything free or almost free in the beginning, before raising it to stratospheric levels once the market is captive. Google did that with Maps. OpenAI is doing it with its API. And people like free or almost free things rather than reasonably-priced things.
It's not always so capital intensive anymore to make things free, there are technical advancements that make that easier these days so I believe there is edge to be found. In particular I'm exploring offline-first apps in addition to decentralization/self hosting, because offline-oriented apps help avoid expensive servers. Users like the privacy benefits and I enjoy the benefits of minimizing UGC custody.
I don't know to what degree that this will be a watershed moment, but I'm hopeful that this is a high-profile enough of a wakeup call that some dedicated subset of power users puts their efforts into developing the ecosystem around federated alternatives that have the possibility of breaking free from extractive models of social media. Even if that's 100 people out of the millions potentially affected by the reddit changes, that could bring a lot of benefit.
