There is an effect, if we consider where the person who is running the node lives and the associated costs to running a node: internet, electricity and the price of the hardware. Here in my country one would not be able to run a full node and keep it on, withiut having to pay for a descent internet connection (which is expensive to anyone here) However, because of the altruistic nature of running a node, so the network can be more decentralized, I would dare to say it is one of the most reliable ways to know someone is a true Bitcoiner which loves this community truly by heart.
I hope to be able to run my own node someday, eventually, at least for a couple of years.
