To be fair, a large part of the ecosystem doesn't actually deal with Bitcoin at all. The total market capitalization of cryptocurrencies seems to reach up to 1.5T USD at this point. Bitcoin is 1T USD of that, with the rest of the ecosystem quickly catching up[1]
It's really hard to generalize that everyone in any given ecosystem are the same way or act with the same interest. Yes, most people in the oil industry probably don't care about the environment either, but I'm sure there are many in the oil industry who actually care about the environment as well. Same goes for cryptocurrencies.
