When following real world procedures (like AV-test and AV-comparatives) most AV's have near perfect scores. The point Cruel Sister was making in her first video is that allowing a dropper through a LoLbin is a considerable risk factor (you don't know whether the downloaded file is good or bad). Her (in my opinion correct) warning that ESET could do better, triggered a bombardment of critisism that the file dropped was not really malicious. That is why she posted the second video (which dropped something harmefull and bricked user files).
Now they are critising
@cruelsister 's video again with the arrgument that it did not come through the "front door". That argument in itself is valid. People can't be infected out of nowhere. But for average PC users the most common routes of infection through the 'front door" are responding to an email with either a prize or an tax invoice. The trick is to trigger an emotion (greed, anger and fear work the best). Another often used rout eof infection is an average home users being redirected to websites looking like an antivirus telling you are infected (using the fear emotion) and you need to download something.
So getting through the front door is trival, but even using the front door approach ESET has its limitations (and CS video shows why they probably missed the 1.8 percent of tthe "in the wild samples, using real world scenario's" in the picture below).

But as @Showdara posted, it just confiorms his experience.
