Just looking at these comments, and the fact that wayland still isn't as good as x11 after all these years (10, 15?) And all this budget shows that wayland is architectually wrong and will never be actually good.
Any software engineer will understand this. If your project is still in basically beta after more than a decade and that much budget, and it's only selling point is that "but it's slightly better than the decades old legacy system", that project has been architectually wrong, and also definitely has awful management, and you call it failed.
