This has happened in the past and then we get odd things that pop up six months later like the tooth-paste ad.
Also, in the Japanese entertainment industry, this is pretty standard practice. Talents are basically supposed to be on call 6 days of the week to record, shoot promos, do photos, or make appearances. Everyone is competing against everyone else for screen time so they (the talents) are at a disadvantage and must sacrifice their time for success.
