Why are people upvoting this? Serious question.
An easy and proprietary deploy layer isn't anything new. Docker makes it already quite easy to deploy anything, either to a single machine with docker-compose or k8s for multiple nodes. Former isn't much harder than any "app platform", is enough for most, you aren't vendor-locked-in and hosting costs are at the lowest since it's bare-metal. You want something easier? There are already gazillions other (proprietary) options.
Maybe I missed something but I don't get what makes DO any special here.
