Verisign is going to push every possible way to extract more money from .COM/.NET monopoly. They maximize price increases at every opportunity on their contracts (which has automatic renewal and no competition). For what? No added value to customers or the ecosystem as a whole.
SiteFinder was just one of many moves in a long series of bad for everyone but Verisign moves. Remember when .ORG had its price caps removed and then private equity tried to buy it? Guess where a lot of that backing came from...
