So I have made up my mind, and I will simply not download any addon that is not maintained through curse. That is THE addon-database of WoW and should stay that way. This is my way of supporting that community and also my way of showing my disgust with tukui for trying make it into a profit organisation, which is ofcourse their right and perfectly understandable. I'm just not following them.
In short, I'll abandon ElvUI and settle for whatever I find on curse.
If you were/are using elvui, what do you plan to do?
You can consider this rant or free commercial, either would be accurate.
