Red Hat is the exception that proves the rule. Canonical and Suse haven't been huge successes from a financial perspective. They've survived mostly by investors hoping they'd turn into the next Red Hat but they haven't. Certainly Amazon, Microsoft, and Google have generated much more revenue selling cloud services based on Linux than even Red Hat ever did selling Linux support.
