I think it's a good perspective but it rather downplays the biggest problem: Hype. He talkes about being "hyped up" and all this "hype surrounding us was big pressure" but it is one of the biggest reasons the game was recieved so harshly. It had been built up into being one of the greatest games ever made. In the end it was a good game but couldn't live up to the expectations.
Also while the game was better on PC, it really was a disaster on PS4 and Xbox One which is what drove it's bad reputation.
I like the game but to be honest I'm yet to finish it. The plot and narrative is good, but the open world is disappointing with far too much reliance on purely combat side missions, often with minimal associated narrative. The world would have felt much richer if they'd put in more narrative around the side missions and found other non-combat things to do in the city. I loved the Witcher 3 which has a lot of story around the side missions. I think CDPR could have take a leaf out of Bethesda's book for CP had multiple narratives running alongside the main plot.
But ultimately the game finishes unfinished - they promised too much to deliver at that launch, so kudos to them to being able to focus and deliver a good core game. It just could have been a great game if they'd managed to develop other elements of the game world.
