This is promotional content that doesn’t even talk about open source. I don’t know anything about ´Leon’ but I’ll stay clear.
If you consider a "promotional content" as a blog post talking about a developer story that includes sharing creativity and experience that may help others who create their open-source project, then yes, please stay clear.
Unremarkable developer life story. Skip.
Could someone put a more appropriate title on this link? The story has nothing to do with "running away from open source".
