There's no lack of transparency here. Linode expressly said in their blog post that no CC details were leaked.
> In addition, we have found no evidence that payment information of any customer was accessed.
The question isn't transparency, but trustworthiness. Either Linode is telling the truth, and this anonymous IRC person with a pastebin is trolling everyone, or Linode is lying (or alternatively, Linode is incompetent and simply didn't detect the CC access). At the moment I'm going with Linode is telling the truth, because honestly, am I going to believe an anonymous person on IRC over a company I do business with?
I'm thinking here why Linode holds CC data on its servers in the first place. Anyone care to weight in here?
Secondly, if they hold that data, it's possible one day someone will find a security breach and will access that data. The best solution is to never hold that data.
Since I don't trust most of the systems I use AND Linode has not denied it holds that data... I'm more inclined to believe in this anonymous IRC guy and err on the side of caution.
If Linode had come out and said "Look, we don't hold your CC number in our database" then I think there would be very little reason to be concerned. However...
