I get that point, and it's the same in some forms of software development. Take IntelliJ IDEA, it's been around for ages, it's commercial, and it mostly works and thus it's been the default choice for many orgs. But you can't patch it yourself. If anything breaks at your org, you just use another IDE for a week. No big deal. But that's the thing about open source software you run in production - you don't need one of a dozen enlightened people on the planet who understand it, most often, you will find one on your team who is competent enough to backport a fix, or come up with a fix after debugging it. I see it as more of a safety access hatch.
