I think it makes more sense to think of it as a two track process. It's not that digital feudalism emerged out of capitalism, the internet wasn't really capitalist to begin with and was more or less immediately captured by private rentiers. Note that almost every example in the article except for the car is a purely digital good, and I'd argue the automotive sector is not overall feudalistic, just the digital parts in it. It's still largely a market where customers pay for cars and manufacturers hire labour.

I don't think the entire economy is reverting back to feudalism, I think it makes more sense to think of the digital economy as its own thing that's speedrunning the exact process we already went through once. Next step is then what, digital commoners and land reform maybe, proper digital currencies and citizenship, actual privacy protection? Feudalism on the internet can only exist for the same reason it existed offline, people flock to fiefdoms because they perform functions in a modern economy provided by a proper state.
