Sure, but this is about IP law instead of physical goods.

This is like if you left your door wide open, and a neighbor peaked in and told another neighbor about your decor or what posters are on the walls.

You didn’t lose anything tangible, but something you wanted to be secret isn’t anymore. Where the balance of blame falls is up to you, but I do think to some degree that if you want to keep a secret and can’t put in the bare minimum effort to even try to protect it then you own some of the blame.
