As such, starting from today, I will no longer participate in nginx
development as run by F5. Instead, I’m starting an alternative
project, which is going to be run by developers, and not corporate
entities:
That doesn't seem to be the case. From what I read on HN, the dev quit because he thought it didn't make sense to submit CVEs for temporary/wip solutions, and F5 thought otherwise.
So as I see it, the developer quit because he didn't agree that a CVE should be opened for a work-in-progress solution that was live on Nginx.
