NMS doesn't have dlc, every update was free. they don't have any other games either (prolly one of the reasons they stuck with NMS), besides the last campfire, and that's more a publishing gig I think. they're still working off the money from 4 years ago and additional game sales, it's one of the reasons people give them so much slack.
they might try to sell dlc at some point, but I doubt it. not only wouldn't it really fit into the game besides superficial stuff, so would look like cheap monetizing, it would probably still generate bad PR.
not having anything besides witcher and cyberpunk also means they don't have an extensive IP catalogue to plunder. any company that buys CDPR would just get a bunch of devs that just shat out one of the biggest debacles in videogame history. no assets and no talent doesn't make it very attractive.
that's actually an argument for a NMS treatment, but it also begs the question where the money's supposed to come from. any money they dump into CDPR won't go towards their next project that, even with their tarnished rep, will most likely generate more profit than cp2077 ever could at this point. it's simply more sensible to salvage what's economically feasible and move on than double down.
what does reputation matter really? for CDPR it was a lot of hot air anyway from lot of people being retarded, and considering EA and it's funky bunch are still in business with all the shit they've pulled and still do, all CDPR has to do is shill witcher 4 featuring ciri (so progressive!) and everybody will conveniently forget cp2077 or at worst reserve their judgment till launch and not preorder outright (lol jk). you know it, I know it.
heck, if they're smart (and considering their marketing department just sold a turd to millions of people) they could even build on that by being upfront and open about it to generate hype and forget cyberpunk even faster.
