Hey, author here. I meant "free" as in full featured - I remember Nomad having features that I quite liked behind the Enterprise paywall.
I'm not sure whether that's a bad thing, though, since the alternative would be having no free plans/editions for those pieces of software at all, or maybe just using them for a few years and the company going bankrupt.
As others have already said and basing on the official docs (https://www.nomadproject.io/docs/enterprise), the few Enterprise-only features left don't really feel necessary to me for small-medium deployments; especially when there's an Ops team that can oversee things anyway.
Not trying to play the devil's advocate here, I'm genuinely interested in what I might be missing with my current approach.
