Strong disagreement. The acquisition happened in 2006. The last few great Pixar movies were in the pipeline already (Ratatouille - 2007, WALL-E - 2008, Up - 2009).
Nobody cares about this, the money they make isn't what other people interact with. It's the things they create.
Counter-counterpoints:
Cars 2, Brave, Monsters University, The Good Dinosaur, Finding Dory, Cars 3, Coco, Onward, Luca, Turning Red, Lightyear.
The (not very original) point is: You can no longer count on a Pixar movie being excellent.
