PSA: Booking Holdings operates not just Booking.com, but also Priceline, Agoda, Kayak, Cheapflights, Rentalcars.com, Momondo, OpenTable, and many more niche engines.
That said, this post seems to pertain to the Booking.com business (which is still a somewhat independent division, as are all the properties/brands in the group), rather than the entire Booking Holdings corporation.
