if it comes to changing the client, "I don't care to vote" is a no as well...
pls stop putting word into my mouth, im not voting and im happy with 22% yes vote.
you still didn't get it?
Forking means, that they have to install a new client.
This was a vote on one big pool. If the participants were not in the pool but were directly in the system, they would have to install or not install a new version (there is no abstention). The not attending (lazy) people would not install a new software, thats why its like a "no". Of course you can say, the pool will not care (whats paternalism in my view), but that's still only 1/4 of the network and the ratio of "lazy" people will be equal.
This system makes sense, because, if you really want to change something, you are not lazy... otherwise it was not worth it...
