Hmm, I don't really think its off by much, especially in Westernized nations where practically every thing is governed by contracts, regulations and legalese. And especially at a management level. You allocate resources to accomplish tasks. If you have a C++ developer, that's a resource. Resource X costs Y and produces Z could be applied to JetBrains licenses or people. Maintence for licenses is quite simple requiring updated payment information, maintence for people is a lot less clear cut and requires communication, and lots of ambiguous judgement calls. It's stale but I'm not sure there's a better word to fit in its place.
Denotation of people on salary as a "resource" is correct, and I'm even OK with including people in a collective set of varied types of resources. "We just don't have the resources to pursue all possible ideas" and the like is fine.
I'm recommending a terminology change to always call people "people" as it biases your leaders to think of them as special and different from licenses, machines, money, and black boxes. (It's not my idea originally, but I've seen it play out at my company and believe it to be helpful.)
