It's fairly well documented that many projects in Google happen because that's pretty much the only way to move up the career ladder, and once the promotions have been doled out then the project loses its original stewardship...until someone else is looking for a promotion and sets their eyes on rebuilding that project. (Case in point, the numerous failed attempts to deliver or even brand/market a messaging app).
Naturally, as is it is these days, any new product or redesign is conceived in terms of an MVP. You could argue that the industry as a whole has taken this concept far too literally over the last decade, to the point of being cultish about it.
I don't dispute the parent poster's point in general, I just think it's more indifferent than lazy/greedy/arrogant, unless it comes to search or ads. That's arguably worse, but Google's reputation for delivering increasingly mediocre versions of its products (or shitcanning them entirely) does precede it.
