Just in the past two years I've seen them develop, hype, and then quietly drop: their VR editor, AR preview tool, Octane Renderer, Substance integration, UNet, ML integration.
It's obvious they have an incredibly difficult time managing their tools when their platform is fundamentally shattered between multiple releases, versions, render pipelines, and now DOTS vs normal workflow. And it's basically impossible for other companies to manage Unity SDKs with a ground that moves that much.
