Of course it is worth it. You can make very good living as remote-guru-consultant with total freedom. All while making similar money to FANG employees (counting stocks, high cost of living and taxes).
OSS developers do not have to be unpaid doormats. If I would be log4j dev, I would probably just wipe out all JNDI related functionality from project. Companies who need JNDI for backward comparability, would have to pay for support.
