  That's due to magic changes in the internals of OpenSSL 3.0.0.

  I'll echo Matthew here.

  We're happy to do bug fixes for our software.  We're rather less happy to do work for free, to debug issues created by corporate policies.  Policies which we have no control over.

  To be clear: RedHat makes rather a lot more money off of FreeRADIUS than I do.  RedHat has shared precisely *zero* of that revenue with me.  Ever.  RedHat has in fact competed with me for business, and is actively trying to get customers away from me.

  At the same time, we get RedHat customers asking us to help them.  They're usually running versions which are years out of date, due to "no upgrade" policies like the above.  When told "just upgrade to a version WE support", the answer is "No, I'm paying RedHat for support!"  Except RH isn't supporting them, and isn't fixing the bugs.

  All in all, we fix bugs, and we're happy to work with people.  But make no mistake, the corporate approach is to leech off of my work, and then turn around and bill their customers for it.  That's allowed by the GPL, but it doesn't make me inclined to fix issues created by the internal policies of a billion-dollar corporation.
