By some accounts, the open source world is about to end as evil cloud empires suck the marrow from fragile open source communities, giving little back. This narrative has taken hold, leading some doomsday prophets to the end of open source sustainability as we know it.

The data, however, suggests something very, very different.

According to two independent analyses of GitHub data, as well as , the biggest contributors to open source projects are—you guessed it!—the public cloud companies. Indeed, precisely because they’re in the business of operationalizing software, not selling it, these companies are perhaps best positioned to fuel, not destroy, open source for many years to come.

As dominant platform companies intent on reaching developers, open source is a requirement, not a nice-to-have. Microsoft initially made waves by opening up to running and/or supporting , while Google went a step further and open-sourced incredibly powerful code like and .

Even Amazon Web Services, the hegemonic cloud leader accused of skimping on open source contributions, can no longer sit on the sidelines of open source communities. While than supposed, it dramatically upped its open source game in 2018.
