Everything. Every time there's a backlash against some new pic revealed, people instantly bring up Heath's like this is supposed to neutralize or diminish people's dislike of Leto's.
Otherwise why keep bringing it up all the time. I don't think it's even a great comparison because by the time we hit November 2007, before we even saw any footage of Heath in the trailer, people were for the most part won over thanks to that pic
Wizard released of him, which was our first proper full body shot of him;

The only thing that kept raging on was the debate of whether he was permawhite or not. Christ that got old. Whereas with Leto we have had lots of pics now, including footage, and people are still polarizing on it.
The most annoying part, apart from the idiotic justifications people make like the ones mentioned above, is some people act toward those who dislike it are either going to call you names like tiresome (you were called that today weren't you
I am Knight?), or act like you don't know what you're talking about.
But it's no surprise since it's the same type of crowd of fanboys who we were just previously talking about with the Batfleck suit criticisms. I wonder did anyone get any PMs about the practicality of Joker being barefoot.
