I'm not sure how TechCrunch do it, but if you have Ghostery installed in your browser, the entire article content disappears as soon as the page loads, leaving you with an empty article.
Adblock isn't doing it, definitely Ghostery, so looks like either they detect Ghostery and hide the article if you have it (the rest of the page shows up, just not the article content/text)... or Ghostery thinks their text is a tracker and is blocking it.
The latest update includes "Click to Play." Just click the Play button to let the script run once.
