GP seems like someone who has an axe to grid. Either against the author or against docker/kubernetes.
He seems to show up with disparaging remarks whenever there is thread linking to that domain
For a very simple reason: Linux/KVM, being a paravirtualized, hard partitioning solution is vastly inferior to kernel virtualization in SmartOS. Additionally, Kubernetes is an order of magnitude more complex to run than Triton.
Whether the author owes me anything or not is irrelevant: I‘d still like to know why he keeps on doing that.
There are a huge number of reasons why this may be the case.
This is, AFAICT, a personal blog and so I, personally, don't believe that the author owes you -- or anyone else -- any explanation whatsoever for what topics they choose to write about and/or what tools they choose to either "promote" or "ignore".
Why do you feel otherwise?
