It doesn’t matter. By licensing its name Marriott is taking responsibility for everything these hotels do, along with the risks associated with that. This kind of event was foreseeable, and the corporation completely failed to avoid the situation by providing training on these sensitive issues ahead of time. I don’t see any reason to cut them slack given how suppressed the Uyghur genocide has been by corporations in general out of fear of China, and allowing Marriott to deflect responsibility by blaming everything on local management is exactly what they would want.

Also note that their apology doesn’t explicitly condemn the hotel’s behavior, it just says that they’re providing training. Definitely riding the fence.
