“Unfortunately, some new non-technical management at F5 recently decided that they know better how to run open source projects.”
F5 closed its Moscow office in 2022, and Maxim Dounin kept maintaining nginx for free anyway. His reward was management overriding the project’s security policy for what he calls marketing-motivated actions. F5 owns the trademark and the repo. It just lost one of the core developers who kept the code running, and he took his work to a fork.
