I’m not a fan of Facebook. I don’t even have an account. But it would be unfair to say they haven’t come up with some truly innovative approaches to large scale infrastructure.

Also, to their credit they are huge supporters of open source. For example the Open Compute Project is still alive and well in large data halls. They are also still supporting the Telecom Infra Project which is responsible for OpenRAN as well as their Open DWDM hardware.

Does all of this work in their favor to support their own business? Absolutely. But that can also be said for every tech company in some form or fashion. But, they still open source it which is way more than a lot of other shops can say.
