I'm not sure what you mean—but it is very important to note that the bulk of the work of creating a new, globally-internationalized typeface, is hard, tedious editing of glyphs and kerning tables etc.

Sure, AirBnB staff were involved, but they did not put in the huge amount of effort necessary to actually create the font. So that effort did not happen on AirBnB's property, so to speak, while AirBnB design staff "got to commission a font" as part of their career progress.

https://airbnb.design/introducing-airbnb-cereal/ is PR puff, it could mean they spent an afternoon or a decade of human-hours on this.
