Sharing our thoughts on why we are open sourcing Pixie: https://blog.px.dev/open-source-release/.

Too much of open source today is just vendors using it to promote paid services, without a community approach. Open-source should be vendor neutral and accessible to all.

We used Apache 2.0 as our license and are committed to keep it that way. As part of this we are working on contributing the project to CNCF (Cloud native compute foundation, a part of the linux foundation) to guarantee its vendor neutrality.
