This is an interesting choice--on the one hand, understandable, on the other, if it looks worse than chatgpt, they are going to get pretty slammed in the press.

Maaaybe they don't immediately care, in that what they are trying to do is head off Microsoft offering something really slick/compelling in Bing. Presumably, then, this is a gamble that Microsoft won't invest in incorporating a "full" chatgpt in their search.
