I've worked with numerous SaaS businesses who run open source for as much external software as possible because it has better economics at scale. They want tight control of software configurations, ability to diagnose problems themselves, quick application of security patches, etc. It's not cheap; you have to hire highly qualified engineers to make it work. The approach makes more sense as the business gets bigger, in the same way that it makes sense at some point to design your own data centers, own hardware, etc. It's therefore not surprising to see large businesses go all-in on open source.
