There's a fairly big difference: JSFiddle is completely anonymous but GitHub Pages and similar services require accounts and at least in the case of GitHub they have a functional abuse team.
In contrast, JSFiddle can take something down but that's where it ends unless the scammer used a dedicated IP which is easily traced to them.
And even then, scammers can always switch to custom domains. It seems futile to block arbitrary code execution unless they only allow whitelisted domains.
The low-effort snark is unnecessary and weakens the conversation. At least make it witty.
JSFiddle is a pretty low tier target that most people won't miss. Github links aren't. Also, I'd imagine Github Pages is more responsive to taking down scamware, it at least requires an account, and has more of an interested in keeping malicious behavior off the platform.
