No feedback yet from Marriott, but Starwood is paying attention. Here's a quote from the official Starwood Lurker from the equivalent of this thread in that forum:
"FWIW, this event was sent to all North American Starwood General Managers last night by the President of the division with a directive to adhere to Starwood's policies concerning all things related to housekeeping, in which the proper replacement of in-room items is covered in detail.
Best regards,
