It’s true — especially the part about miners. People who just point their hash at a pool without running their own node *and* building their own block templates aren’t miners. They’re just hashers — outsourcing control and renting out their hashrate, usually to some shitcoin-friendly pool that decides what gets into the timechain.
Also people who hold their coins in self custody, but don’t use their *own* node to move them are just a LARP bitcoiners, because they still use third parties to transact (adding a layer of trust and losing privacy in the process). Still, given the current fuckery of Core devs, running Knots is the preferred method.
