I do see that these particular site owners don't mind their users using Ghostery and uBlock. Some may not go out of their way because they see it as their users denying them ad revenue or analytics (the user is "hostile".) A similar situation happens with NoScript, where some site owners view Javascript as a basic, easily-met prerequisite to using their site, and will do nothing to help users who don't want to enable JS.

I presumed that's what themartorana was referring to about why they might not bother to fix it, and why I thought it would be useful to point out that according to the error message you got, themartorana's site is broken in a different, more fundamental way.
