That's down an axis of "strictly worse than the alternatives." With an open-source ecosystem, I have to set it up and maintain it myself, when it breaks I have to service it by myself (often without a useful community to assist, because my problems are often unique to my special-snowflake configuration), and if I get attacked I'm 100% responsible for digging out of the assault with no recourse or assistance. None of these are concerns with either Google's online offerings or the offerings of most startups.
