IIRC they fixed various bugs but they didn't fix the broken promises. The biggest problems with Cyberpunk were architectural, things that would basically require redesigning the game to match what was promised.
86% of all-time Steam reviews for Cyberpunk 2077 are positive, and if you only look at recent reviews, it's 94% positive.
I don't think the game has architectural problems that prevent it from being a massive success.
After tons of patches and DLCs its just became a very very good game. Just not what was promissed.
Most customers only hear about a game when it is released and reviewed and/or recommended by a friend and will never have heard about them.
Nolife hardcore fans will also be the the first to buy your game, review it and tell everyone if they did not liked it.
CDPR got huge amount of trust after Witcher 3 and they mostly had to start over after CP2077 release.
EA can survive if 4/10 of their games flops completely, but company like CDPR will likely just end there.
...which was a complete shitshow on release as well...
