If we're talking about Yamaoka's biggest sins, they were probably joining up on multiple sub-par SH projects in the first place. Dude wants a paycheck sure, but all the old alumni knew what shit looked like and stayed away. Sato wouldn't be caught dead adding his name to something like Homecoming or Downpour, and he certainly wouldn't have considered coming back for a ""remake"" unless all the old staff were rallied and thought they could actually do some good. Yamaoka is kindov a sellout when you get down to it.
But worse than him (in my opinion) is Ito. Because back during the """HD""" collection days, Ito was very vocal on twitter about how everything was getting fucked up. He was commenting about how shit the collection was, how poorly it was optimized, and how bad the texture work was. Yet this dude signs on to put his stamp of approval on BlooperHill a decade later? Once again all of the old team, the ones who ACTUALLY understood SH, the writers, directors, producers, and Sato, all of them stayed away knowing you can't remake the magic... but Yamaoka and Ito come crawling back as if putting their names on the box means anything. Konami, who obviously doesn't nor ever did understand what they had until it was gone, put their names out front and center during the initial reveals as if the music man and character designer were the special sauce needed to make a legendary game.
It should be quite evident that employees like Yamaoka and Ito were given instructions from the directors and producers on what to do. Yes, they both had creative sparks that added to the formula, but they filled roles that were given to them by the actual movers and shakers of the series.
