In a way, Google's brand functions almost like an ol-school conglomerate-- you've got B2B and B2C products under one roof, with wildly different quality expectations, but all weighing on the brand.
What sort of blowback do conglomerates see for this? Do railroad executives balk at buying GE locomotives because their GE refrigerators fail?
Once upon a time similar things have been said about other giants who fell upon hard times, or died, or had to become shells of their former selves. It’s not like Google has made good friends with the business world either. Besides, the core of their business is advertisements, and they should probably pay attention to the slow, but inexorable backlash against advertising. Given that only a minority block ads and protect their privacy today, it may seem like that’s a silly thing to say, it history suggests otherwise. A bit of goodwill earned while on top can make inevitable slides down the mountain less fatal.
Google fairly obviously is not doing that.
