I am very technical. I was a dev, and can maintain a linux server no problem whatsoever. My main problem was that I had to use a crappy connection in a crappy situation and didn't want to put much resources into it. Plus I don't need it, I really don't have the economic incentive, only some personal/political incentives that are not useful anymore, because the network is already perfectly stablished.

And yes, running a bad node is bad for everyone, specially for those you are connected to.
