@lord-of-the-lost "Opera Software" is a single company, it should not waste money anywhere. Unless it wants to break.
GX, imo, is a temporary product made more likely for marketing purposes; some day it will be discontinued. Perhaps the broken One ui will be force-pushed into it even before it is discontinued.
One ui shouldn't have been pushed into Stable channel yet. It is clear Opera Software doesn't have developers capable of fixing it properly, and so the worst decision was made: rush it the way it was (a big unstable mess).
One may argue that Opera is trying to earn more money with such marketing partnerships . Well, it has been doing that for several years already, but the quality of its product is only decreasing. Inefficient strategy.
