This is true! You don't have to agree with them, though. The network still exists and is cool and useful regardless. You don't even need to use Reddit! I don't hang out on reddit.com/r/visa (does it even exist?)
>> Not to mention that Bitcoin is explicitly anti-environmentalist
I think it would be fairer to say that it's 'a-environmentalist'. The badness or goodness of energy use for PoW just wasn't really a concern.
When I play Quake 3, my computer uses more energy. I consider that an acceptable compromise. Perhaps there are people out there that don't, so they don't play it.
I would find it quite odd if they criticized my habits, though. We should be trying to get along, not looking for chances to grumble at each other, you know?
