Looks like Nintendo is not to be trifled with. The company has achieved the dismissal of a GameStop employee who leaked the announcement of a themed Nintendo Switch for The Legend of Zelda: Tears of the Kingdom. told about this Mike himself.
He revealed that he did this because he is a big fan of the franchise and wanted to warn everyone that pre-orders will open soon. Initially, there were no problems, but then Nintendo intervened.
The company figured out Mike, and then GameStop management contacted him and fired him. Moreover, initially they stood up for him, because the employee did an excellent job, but Nintendo insisted on its own and even threatened with sanctions towards GameStop and cooperation with them.
Mike himself did not hide any information about himself, so it was easy to figure him out. The moral of the story is: beware of Japanese companies and respect the embargo.
