I don't think it qualifies as speculation anymore to assert that Google has something really broken about it, organizationally, that keeps it from producing truly good software—and often not even decent software—in most of its projects, for some reason. Even very high-profile ones. There's not really any other explanation for how they consistently behave.
The rest of Google has other priorities though. Even gmail’s iOS app had pretty glaring bug that it couldn’t mark a message read.
Google docs fails to save at times. YouTube Kids is just an awful mess. Don’t let your kids even near it. Google Cloud isn’t as reliable as the other clouds. Google can’t do proper human support. They don’t believe in it. If you’re a small shop, going with Google for anything critical is just going to be a disappointment.
Google Search though. I have an insane amount of respect for their engineers who work on performance and reliability.
