Yes you can add content to something you're proud of but you can't fix something if you don't acknowledge something is wrong. And I think that is the root behind people who worry about the "proud on pc" bit. Zero acknowledgment about the incredibly enormous gap in gameplay between what was offered and what was delivered is understandably worrying.
The thing about acknowledging ... issues, might be cultural, and it very well could be legal.
There's also the bit where some folks with at least $1 Million in stocks invested in the company probably have more "important" opinions that need to be addressed than some gonk that just can't seem to deal with driving a video game car, or any number of things that are mostly non-issues.
For instance, culturally, CDPR very well may want to acknowledge issues, BUT only AFTER they are fixed. That way, any acknowledgement isn't just empty words. It's"veni vidi vici" ... or, "I came, I saw, I conquered"; or we heard you, we took note, we fixed these things ... you have proof we fixed those things, now, with better faith, we will continue to fix the other things and continue to work on improving game.
Legally, the lawyers could be saying to STFU and that ANYTHING they say, until something is actually fixed, puts them in even greater legal jeopardy.
There's lots of very good reasons for CDPR being tight-lipped.
The doomers ... sheesh. Some of these people act like they've never ever bought a game right after release. Does anyone remember all the bugs when The Witcher 3 was released? CDPR even puts an Easter Egg in the game making fun of itself with the Roach bug, where the horse ran around with it's rear end way up in the air. There's a sticker of a horse in that position on your very first car!
Have these people just not been watching gaming news for the last 20 years?
Sure, this isn't a smooth release by any means.
There has, however, been far worse, and to some degree, pretty much every game released these days has some issues directly after release. Anyone having fun with all the circle dances in Assassin's Creed Valhalla where fighters get locked in a spinning circle dance?
Anyone ever hear of Fallout 76? Battlefront? Anthem? No Man's Sky? eh.
... and there's lots others that were just so ridiculously poor, not so much bugged, but just poorly done and that list can stretch out to the moon.
Ah well. Be patient. Wait a minute. Wait a minute more. Things'll get fixed and the game will get better.
