The change licence in Directus simply seems to be GPL3:

The only provision they have added is that if a business uses it in production and that business has >5 revenue/funding then they have to obtain a commercial licence.

Yup! It's a delayed-open-source license that auto-converts the code to GPL-3 (a "normal" license) after 3 years. It's free to use for non-production, and free to use for companies / individuals with <5mm in finances. It allows us to make the project sustainable, without punishing the folks who've historically contributed the most I wrote a more in-depth how/what/why in the thread above~

A sustainable project income can be hard, I get that, but an auto-converting license sounds like some kind of trick weapon, not like a real GPL-3 license.

I suspect that weird versions of "open-source" licenses are rarely good for any party involved.
