why is a Bloomberg reporter an expert on cdpr/cyberpunk? because he got hits with some halfazzed articles?
No, because he interviewed the staff. Some of them even let him use their names. Also, he is a journalist. If he publishes something that isn't true, he he can be sued for libel or slander. That did not happen. In fact, as far as I know CDPR have not published any official replies to Shreier's tweets and articles.
I would say Covid 19 is what made this game go wrong.
This was surely a factor. But many wholesome AAA games were published in 2020. Obviously, with how broken and unfinished CP77 turned out to be, it must have run deeper than Covid-19.
The state of the game aligns perfectly with what Shreier reported. It's not unreasonable to believe it even for the biggest media sceptics.
