It looks like the the American and Canadian Red Cross(es) actually sell first aid supplies with the emblem: https://www.redcross.org/store/first-aid-supplies, https://products.redcross.ca/. Is the issue that the emblem is on first aid supplies at all, or just first aid supplies made by other organizations?
I don't really get the connection between that activity and:
> In fact, the red cross emblem is an important symbol of humanitarian protection. It is recognized as such in both Canadian and international law which prohibit its unauthorized use. Misuse of this valued symbol distorts its meaning and its protective value for victims of conflict and the aid workers that assist them.
