Absolutely correct. But this is the website owner's problem and their consequences for not using SSL. You can't help or prevent this because it's not your server, it's not your fault they enabled insecure communication that can be exploited. When you forgo SSL on your own server someone can also intercept your script in exactly the same way, they don't need to hack the website embedding your script. Now they are your consequences, your fault there's no SSL, and your problem may be affecting everyone who embedded your script insecurely.
