I'm not familiar with what's happening in this Redis licence change.

But if it was Open Source at version N, and you built your business (or stack, etc) on top of that, N will remain forever available to you as FLOSS, not?

Is the problem maybe that ppl expect future updates, maintenance to remain Open Source? Something that, AFAIK, no Open Source licence guarantees? So, misaligned expectations?

> That's not the case any more - not just because of Redis, there are a number of other high-profile license rug-pulling projects.

It's not new. MySQL, Redhat and many others have done this for ages in the floss community.
