I thought that phrase sounded familiar... the author's term is perhaps inspired by the article "Farewell, Millennial Lifestyle Subsidy" published in the New York Times almost exactly a year ago, which also discusses Uber pricing as an example. (it got posted several times on HN but without much traction).

The Atlantic author in 2022 says "I call this the Millennial Lifestyle Subsidy", not offering credit to anyone else, but back in 2019 he was calling it the "Millennial Lifestyle Sponsorship", with that phrase linking to a tweet by the same person who later wrote "Farewell, Millennial Lifestyle Subsidy" for the NYTimes, seeming to offer him the credit for it.
