They’ve already won the phone market, the server market, and the professional workstation market. We’re just bringing them to the Linux desktop which has traditionally refused to adopt new technologies in a timely manner.

Thanks, but no, thanks. I don't need my desktop to be a container. And that's not a new technology by any means either. Immutable distros exist for years, for example OpenWRT. They have their uses like embedded scenarios indeed, but it's counter productive on a general purpose computer. Turning it into appliance and then looking for loopholes out of it when you realize you need a general purpose computer and not an appliance is a somewhat strange idea.
