Ultimately the market decides who's *private* interests win. You can't know those interests. Hence "private". Only the market can decide what the best money is; not any shadowy group. To believe otherwise is either naive or has an ulterior motive.
I don't belive the spam (data storage) presents an endemic, catastrophic issue for Bitcoin. Bitcoin can handle it. It was designed to handle it. The content of that data, may be another story. But the point I'd like to make is that the problem I see is with the centralization of Core development and the effective unilateral control they have over the entire network. Anyone that feels like a certain group of people should be the ones writing the code used by planet earth is not acting in the best interest of Bitcoin.
The "people" writing the development code should be all of us. Not one group, controlled by private interests. That is objectively what has happened. That is why I run BIP110.
