If a FAANG releases Kafka, REACT, Kubernetes, or any number of projects that they found helpful, and released into open source - there will always be a claim that they do it with some second intention, such as "be seen to be a positive contributor to the community"
But the truth is - so do I - as a humble contributor to a document, test, bug fix, or feature add to a FOSS project - where's the beef?
If only, those FAANGs with hyperscaler and AI business always have a way to plunge those improvements into customer acquisitions for their cloud products, not available on the other vendors.
