Companies, not only gaming but in general, invest a lot to marketing because that works. I think people greatly overestimate how much people think of companies behind products. I have bought one game from EA since ME3 (NFS: Heat from sale) but in larger scale, if customers were practicing some sort of discipline in what they buy based on their past experiences, EA and Ubisoft wouldn't be in business anymore.
The fact is that, for all that people complain on social media, I don't think that many real world people feel that way. Social media has a way of amplifying things beyond what is normal or reasonable.
The sales they got was a lot of goodwill from previous titles and marketing PR.
Whatever they do next - even if its literally the best game ever made - will be a monumental step down. Literally because all of their goodwill is "cashed in".
CP2077 was my first CDPR purchase. I purchased TW3 because of CP2077.
I can attest that CP2077 on PC is a fun game and one can play through the main quest to the end quite easily. There are bugs, so save often, but I never encountered anything that prevented me from completing the game. In the end, I would not hesitate to suggest that a PC player buy the game. There might be games that are better value than CP2077, in terms of story, graphics, game design, performance, open world, quests, or some other opinion, but that does not mean that CP2077 isn't worth buying.
Now, do I think that CP2077 is a game that people are going to stick with for thousands of hours? No. Do I think that the modding community will be robust and add to the longevity of the game? No. CP2077 is a play-it-and-move-on game, and it is hardly alone in that field.
Will I buy another CDPR game? Sure, why not. As with any other studio, it depends on the game.
