It makes the game stay in people's minds longer because people keep coming back to it asking "is it good yet, have they fixed it yet?". It kind of feels it has worked like that for Cyberpunk. If it's a finished game on launch day people will quickly make up their minds if it's for them and then move on.
Personally I would be on the fence about buying it even if it was good on launch and I would probably not buy it straight away. But I might just change my mind if I get reminded of it enough times. Then again I felt like that about Cyberpunk as well and I still haven't bought it.
