I suspect what they mean by "max 5 user" (based on my experience dealing with enterprise software vendors) is that the terms of the "community" support plan covers deployments with up to that many users - i.e. there's nothing technically stopping you from creating more users, just that it would be outside the terms of whatever support contract exists for that "community" "price" tier. This is consistent for a lot of enterprise software out there, where the software won't necessarily prevent you from creating more users than you have licenses/seats for, but the vendor will absolutely bring this up when negotiating a renewed support contract. Only difference here is that the support is licensed separately from the software itself (whereas for proprietary enterprise products they're usually one and the same).
