According to Coindance, almost all nodes still support Core. btc1 nodes (Segwit2x) have almost no one using it.
There's a difference between running a node with X software, and supporting the positions of the related development team.
Talking as if running software = support is something that needs to stop. It's not correct.
I run a bitcoin core node but I often do not agree with the decisions made by the core team. There aren't millions of clients to cater to everyone's minute differences of opinion, so it's not exactly easy to 'show' your support in this manner.
I realize that not everyone is going to support every decision Core makes, but I would assume if someone supports Segwit2x they would at least be running the btc1 client. What is the rationale for not running a btc1 node if they have the intention of hardforking off the Core chain in November?
