Feels to me like it's entirely sidestepping people's actual complaints.
Yes there's a lot of misinformed people attributing faults in Bethesda games to the engine that may or may not be caused by the engine.
But people are using "engine" as shorthand for "technical problems existing in all Bethesda's games to some extent since Morrowind".
People wouldn't care about the engine if these games had good facial/walking animations, slick movement systems, few graphical/quest/NPC bugs/glitches, characters with eyes that suggest life, streamlined area transitions etc.
Me and a lot of people really love Bethesda's games for the things they get right, but hand-waiving complaints about their serious technical problems as being from people that don't know what "engine" means is not particularly constructive.
Obviously, no one else makes games quite like Bethesda, so you accept the rough with the smooth, or at least the market certainly does, but I can't' blame people for wanting Starfield/TES6 to at least approach industry standard levels of polish.
I guess every player has to decide their ABABAPPA for each game on a case by case basis.
