There's a lot of helpful information in the article, much of which I didn't know about. I'm glad that you took the time to link to specific issues, that's very helpful. However, the article is so incredibly negative in tone, and so thoroughly dismissive of Docker that I have a hard time taking it to heart.

Docker is not a silver bullet, and it is definitely being over-hyped right now. But it does have some great usage cases, and it has got a lot of people working together on re-thinking how we build and deploy applications. I think you'd be more likely to bring about positive change by adjusting tone and trying to point out some usage cases where Docker excels. I can't speak for everyone else, but I'm a lot more likely to take someone to heart who shows some balance while criticizing.

Unless you just wanted to get lots of page views with an hyper-critical (though well-researched) article. If that is the case, carry on and disregard this.
