Thanks to great input by @bmarwell.de, verified bluesky now also supports Apache Foundation Member verification 🥳 Thanks a lot!
With the same update, I have also removed support for conference verification as there was very limited demand by organizers and speakers

JUnit is undoubtedly one of the most important projects in the #Java ecosystem. And it's 100% free and open!
Let me be frank: If we can't get THIS project to the point where a single maintainer can focus on it, then what does that say about our commitment to Free & Open Source Software?

"Nobody stops in to check on you. They check on the project. There’s also nobody standing up and saying, ‘hey, thank you for the good work you’re doing to remediate this issue.’"
The harsh truth: maintainers give their spare time, yet positive feedback is rare.

I never imagined GitHub would ask me to speak about #Log4Shell.
But it happened.
@github.com asked me to share the story as I lived it, for the benefit of users of #opensource. How could I say no?
I hope it helps build a more secure future.
No more Log4Shell.
