Makes sense to me. A chat UI has more avenues for subtle advertising & sentiment manipulation than plain links do.
It is weird that they're putting all their eggs in one basket though. Wouldn't a more sensible business move be to launch that platform (and advertise it heavily) but maintain the old search UX to fend off competition?
Going all in like this carries a very real risk of burning users onto other platforms and the continued evolution of integrated search bars are already slicing off significant user segments.
Yeah just giving you the information/solution doesn't pay the bills. It's why supermarkets frequently change the layout of their aisles.
Never give the customers what they want give them what makes you money.
