Ted Tso gives some insight on the LKML on the Red Hat & IBM approach to software
From Ted, the ext4 maintainer, on the LKML a few days ago.
The thread is about mainlining bcachefs but the post from Ted, who from what little I know seems about as trustworthy as ext4 has been over the past few decades, gives an interesting overview of the business approaches to software of IBM, Red Hat, Google & Sun Microsystems.
Of general interest to myself but mainly posting as it seems relevant to the recent changes in RHEL, CentOS, Rocky, Alma & Fedora over the past few weeks/years and gives some context of how we got where we are from ~2010.
