Don't they have one GUI library team? Nope. They don't even have one string object or math library. When I talked to a guy who worked on Mac stuff for Adobe, he said that pretty much anything that could be shared, isn't. Every flagship product is independent, and most were the result of at least one acquisition (some circular!). Pretty much every effort they've made to rationalize things into a coherent suite has just resulted in regressions, as none of the object models line up. The engineers at Adobe know full well how shitty their flagship products are. Lightroom is what they can produce in green-field development, and it is awesome both in implementation (mostly Lua) and usability (no bloat). Apple's Aperture had a significant public first start, and was still quickly beaten with a superior product. Quite unexpected.
