I think you're confusing them with wework which is famously know for being a real estate company masquerading as tech. Airbnb has made some non-trivial open source contributions that I'm aware of at least. There's a very popular eslint style guide based on their internal policies and they've also created an svg animation library (the name eludes me) which is popular with designers as it accepts Adobe AE as input.
