Linux which is better than not
RedHat used to be a pioneer within the Linux enterprise world but has since 2018 started to lose itself. You cannot even access certain forum posts with fixes or even tutorials without an subscription. Ever since IBM acquired RedHat one cannot fail to notice how the new owner despise "FOSS". The ever increasing small steps to remove free features and add ever scaling monetization to... everything. Funnily enough Redhat is still based and dependent on the OpenSource idea of Linux.
