Envoy is indeed open source and freely-available for corporations to use. That is not what I was implying.
Amazon, out of all the big companies (Google, Netflix, Microsoft etc.), is the one with the least contribution to the open source world, despite using many of open source tools to build their AWS products.
This has become a bit of an interesting topic to me because it keeps being brought up by people who sort of just state it as fact without providing any real argument. How much is enough? One full time developer? Ten? What if the project doesn't want to merge their contributions? Amazon just got killed on HN for open sourcing all of their ElasticSearch work in a separate repository.
I feel like they can't win on open source with some of you guys.
On these figures, Amazon is behind other giants and has fewer contributions that a number of midsize tech companies like Red Hat or Pivotal (my employer).
And are github repos and stars the only way to measure open source contribution? The Xen project only has 162 stars, yet I don't think anyone would say it isn't an important project, and it's one Amazon has contributed to - if you're using a PV guest on Xen that's protected against Meltdown, chances are high you're using the Vixen mitigation that Amazon released.
Could Amazon do more? Probably. I'm not trying to say they're perfect. But this idea that they don't contribute back to open source seems pretty flawed, even by the data in your link, which seems incomplete.
But unless Amazon are hiding several hundred contributors and thousands of commits in a repo that's been magically overlooked for years, the figures tend to make them look bad.
For some reason Amazon just doesn’t want to show they had any involvement with that commit and doesn’t care about how it’s seen. From the times I’ve seen it, seems like this might by by design
