Here is my understanding of author’s position: Stay away from companies like Redis and ElasticSearch. They are building software with a proprietary mindset (the fact that they have tight control over product strategy and development demonstrates this) only to realize that they are being devoured by bigger fish. It’s a business model problem, not an open source problem.
So what’s the better business model, is what I would ask the dude.
Which is why I say they live in their land of make believe. It’s great to preach principles when you’re not the one impacted sticking to them.
