I think on this site anything that's more expensive than free is considered expensive. Countless arguments have been had on Oracle vs Postgres, including lock-in. I think lock-in is more important to consider than license cost. To be fair, it is quite nice for the pricing to be transparent. And I think it's somewhat competitive w.r.t. Stardog, for example. The community version is less restricted than Ontotext, for example.
