There was an almost exact example of this: City Skyline 2. It's (was) a poorly optimized game and they said Unity's DOTS didn't match their expectation, making Unity look bad, while some issues (like they didn't use LoD where they should have) weren't Unity's fault.

And even in this case, it'd be extremely weird if Unity published a blog post about how City Skyline's studio is a "Just a total shit show, from an employment perspective" (quoting Andrew word by word here).
