I added some color for you. Misconfiguring a node with some ridiculous maxconnections (running it wide-open) is possible, and even a nice thing to do if you have unlimited bandwidth. It's also nice to tip your waiter $500 when you go out for lunch.
Allowing more users == misconfiguration for you? The analogy does not fit either.
Do you honestly not understand what I'm telling you? Tipping your waiter $500 on a $20 meal is also, technically, not a mistake (misconfiguration), but only if you understand that you're leaving an unusually large tip & can afford to do so.
For those of us living in third world countries, on <$1 a day, OTOH, leaving a $500 tip
would be a mistake.
In all honesty tho, I doubt they go out to fancy restaurants anyway. So the entire issue is as moot as the cost of running the node which they do not run anyway (because they can't afford to use bitcoin).
