Did the curated compatibility view list in IE10 just become a black list instead of a white list?

The Modern IE 10 browser is becoming flash-capable by default starting tomorrow. Most of the time, this wasn't an issue, because IE 10 was always flash-capable, but just blocked sites requiring the flash plugin by default. Instead, it employed a compatibility list of websites using flash, and the most heavily trafficked sites were on it. Some sites, such as YouTube, allowed for html5, so again, barely an issue. Now, it looks like Microsoft just flipped the white list to a black list, and everything's hunky-dory. Oh, except if you were one of those "smarties" who hacked the white list to put your favorite site on there before the curators put it on there for you. Congratulations to you. You were king of the Internet for 5 months.
