This is such a weird argument to have when incentivizing w3schools to use SSL would be a good thing. They can clearly afford the cost of acquiring, installing, and maintaining an SSL certificate. And as a website that teaches people about the web, they should be setting an example by using SSL. Alternatively, they should be setting an example by demonstrating that password prompts that aren't over SSL will cause warnings.

But even if it were legitimate for w3schools to not use SSL, security is about tradeoffs, and the tradeoff is that it's absolutely worth displaying a warning on one page that arguably doesn't need instead of not displaying it on millions of pages that definitely do.
