Proton says all the time, they are obligated to comply with the letter of the law, so do not store anything identifiable anywhere they’re legally required to provide it. They tell you exactly what not to do, to avoid this precise case. They do not want to provide anything they don’t have to, but they also do not want their company shut down.
Passing reminder that Goro Miyazaki is an architect who never wanted to make movies. He was brought on as an architecture advisor, and the studio kept pushing him to take more and more responsibility because he’s his father’s son, and his father encouraged it. The movie sucks because he’s not a director and he didn’t want to make it.
(Side note: I actually rather like Tales from Earthsea, so when I say it sucks I’m referring to general public reception and not my own opinion.)
