It does look good from that photo.
Perhaps, publicity of the "doubtful" kind can make the owners change their mind. Albeit I am dubious. One day, I think, the law will catch up to include "cruelty to fish". Then and only then one could do something about it, IMHO.
Many shop owners feel they need to have an attractant, a bait, a lure and it does work for them. This RTC may be it. For every hobbyist who knows what he/she sees, there are 1000 that don't. So the ratio is very heavy in the owners' favor.
