At the very best, "freeloader" is a term used by someone internally, but I've never ever heard it used in over 10 years in the company.

Full disclosure: Red Hat employee, not writing in the name of the company, views my own and all that. I'm also pretty pissed about CentOS dying, and like many Red Hatters, have voiced my concerns internally. I also happen to think that a lot of the online criticism is unfair, incorrect, and sometimes done in bad faith. So I'm trying to be accurate. As far as I know, nobody in Red Hat calls or even thinks of CentOS/Rocky/Alma/Oracle/... clones as "freeloaders".
