This is "open core" model and it won't fly (and that's a good thing).
They want to compete with an established, mature free software project. You can only do so successfully in the long run if you stay 100% free(dom) software. Why don't they sell real adaptations (not basic features they actively deny) + support?
That's some other model it is up to the owner to choose their business model. You may not like it but encouraging others to ditch software on this decision is not healthy IMHO.
