If it was free, we&#x27;d see a lot more of it, I am convinced.<p>&gt; If you like, substitute &#x27;competence&#x27; for &#x27;prowess.&#x27; Running Ubuntu is like running Windows: it&#x27;s popular;<p>Isn&#x27;t the ability to quickly ship a stable, reliable product that customers are happy to pay for,  a better sign of competence than say picking Slack or FreeBSD for server for now good reason except to show competence?<p>The question is who is the show of competence for?
