Should we oppose any Crypto-currency which attempt to Centralize and/or Concentrate power/trust to a few individuals?

I ask because it appears that many of the ideas proposed as alternate currencies add centralization to the Bitcoin model rather than attempting to mitigate Centralization of Power. I view *insert name of alternate crypto currency in question but which shall not be named* as being one example of this. To me, these currencies are simply short term currencies whose point of being is to give the backers some short term gains by selling pre-mined coins or by abusing their own code to extract more coins than other users. In other words to get a one up on the competition and thus make money.

Am I right to be skeptical?
