Call me dumb if you want, but I was genuinely expecting to see a roadmap, because I would have never expected someone to try to charge for something like this.
Why would you not expect someone to charge for this? There are many services that charge for hosting private packages (rather than making them public to the world); I'm not aware of _any_ service that does so for free.
I read private, and didn't notice the word hosting, so I thought it was an on-prem package indexing. Uploading their proprietary code to some random hosting provider isn't something that would fly with any of my clients, so I didn't expect that. Whenever I see a product landing page with pricing, they title it Pricing, so calling it something else sounds like someone playing coy with the fact they're a payed product. Compare with Artifactory, which is up-front about it, and offers much more than just a package index.
