My recollection is that there was an intentional limit on what parts were compatible with what ventilators, essentially DRM or filter tying/bundling. This denied healthcare facilities the flexibility to pair consumable components from third-party manufacturers with a specific ventilator. (I've been looking for articles to support this without joy so far, though there were numerous articles on "open source" ventilator concepts, such as this one: <https://journal.valeriansaliou.name/makair-series-the-inception-of-an-open-source-ventilator-project/ https://journal.valeriansaliou.name/makair-series-the-incept...>.) This goes above and beyond basic market function, though yes, I suppose you could say that it was rooted at some level in capitalist short-term-profit-maximising practices.
