The offering by OP is a fairly common and accepted structure, and this seems like an unwarranted nitpick?
Another org with a similar offering is Elastic, who offer Elasticsearch as a "Free and Open, Distributed, RESTful Search Engine" per the Github repo. No-one is going to be complaining that they don't offer their full platform under an open source license.
Offering a self-hosted version of your core product with an appropriate license is standard fare.
