True from a purely technical point-of-view, but doesn't take into account how companies make decisions about adopting platform tech and that they're making these choices for good reasons. When companies choose SF or DB they don't make a decision to install one of these platforms because there is no combination of open-source components and bespoke engineering work that could replace them and even be more flexible and efficient. They are choosing these platforms because they make it easy to manage data operations holistically, because it's easier to hire people who already know them well, because they are opinionated and restrict the range of bad or just strange decisions someone in the organisation could be making if they were not restricted, and of course for enterprise support, available from a single reputable vendor.
