How it is namely Ethereum public good.
"The individual people, organizations, software, ... that create, operate, maintain, use, analyze, or convene around the Ethereum Protocol or anything built with the Ethereum Protocol."
So, it convenes people to use Ethereum protocol instead of Amazon and benefits people and organizations that can earn Ethereum with both blogging or sales. So it benefits people that "operate" around the Ethereum protocol.
And lastly it is creating software around Ethereum protocol.
Side note: Constitution needs to be more clear. But now it is on my side. If it is wrong, correct it, but don't judge like wikepedians who ignore the rules they themselves wrote but instead delete everything they just consider "outside".
