I think the ramifications of NEM somehow stepping in and telling Maduro et al, "No, you may not use our block chain!" would be pretty sweeping, and probably more of a detriment to whatever good in the world cryptocurrencies can accomplish than the "good" of prohibiting a "bad person" from doing something crazy with a cryptocoin. Just imagine that NEM got taken over by bad people (Maybe Maduro himself launches a coup and takes over the NEM foundation or something), and decided that no "good" organizations could ever build anything on NEM. Then what?

I think it's honestly better to keep it open sourced and decentralized, and see who uses the technology. I've heard of at least 7 or 8 tokens launching on the NEM block chain, so it won't be long before Petro becomes just one of many others.

Apparently Bankera is under investigation by the Lithuanian central bank. Bankera is soon to be a NEM token. Does that make them bad too?
