Also, commercial open source != free. You can't use Docker Desktop commercially without a license and it's not 100% OSS. Many companies use open source-washing as a way to lure customers into yet another proprietary system that dresses itself up as FOSS.
Furthermore, most commercial open source community versions are crippleware hiding useful features behind closed-source, paid-subscription-only offers. And, the CE versions are usually out-of-date and are slow to receive security updates. SugarCRM comes to mind.
