Yakuza Games on GOG Exclude Numerous Developers from Credits

The recent rereleases of seven games in the Yakuza series on GOG have altered credits which exclude numerous staff members from the primary Ryu ga Gotoku development team as well as some entire support studios.
First noticed by reddit user u/Timo653 and reported by PC Gamer, the removed staff includes studios Lab42 and QLOC, who worked on porting the games to PC, and even some very major players in the games’ development.
These major players include series directors Toshihiro Nagoshi and Daisuke Sato, both of whom recently left Sega in 2021 to form a new studio called Nagoshi Studio. u/Timo653 noted that some of the other names removed were also former Sega staff who left to join Nagoshi Studio, including Yakuza 0 director Kazuki Hosokawa, but this does not seem to account for all of them.
