At least a few of the comments in that Reddit thread are from people who knew of Evans but did not know of his recent scandal, even more than two years later. So it shows how topics like this one still serve a purpose after all this time- there are still people who only know him as an exJW doing "good work" against the WTS. And they don't buy his bullshit explanations for why he is a bad husband and father.
At this point, I doubt any of his patrons are unaware that something happened. And it's pretty easy to find out the details. They can get most of it from Evans himself.
