I always check the license first and this is not too nice. These mixed licenses are a real nightmare for companies and their lawyers. Keep it clean & simple or there won't be a lot of adoption really.
We're using the open core model that Gitlab use. It's popular because it mean 95% of the code is MIT (good for everyone) and a small number of enterprise features are under a different license. This puts off bad actors from building a commercial competitor with zero effort. The alternative we considered was AGPL but that felt worse for our open source users.
