This quote "By that I mean the freemium model should offer the client the chance to grow — equality of opportunity — and if it does happen that they grow and become profitable, the SaaS starts charging based on that. In a sense, value-based pricing, or at least as much as it could get with a scalable model." kinda implies that your client is a business ("become profitable"). We have teachers as primary users, and I don't think the general arguments apply to that category of users (although freemium is still a very popular pricing model).
