CD Projekt was considered a solid developer before Cyberpunk.
However, Cyberpunk was (completely) broken during its initial release 2 years ago (and still is on some of the platforms). The industry is in shambles if this is what meets expectations.
You are mixing separate problems. People still bought 20M copies, that's a success in itself. That said people buying 20M copies of a "broken" game is certainly a depressing trend - same with people supporting games riddled with microtransactions.
I'm a release-day player and I can honestly count the number of "annoying" bugs on one hand. However, I had a decent PC and the state of the game on last-gen consoles was ridiculous and unjustifiable. That said, the game was incredible.
I can't think of a single high-profile launch in the last 5 years that wasn't riddled with bugs.
