I feel like the blog post could largely be summed up as "stop threatening to remove the normal HTTP API, some of us find that a lot easier to debug and ease of debugging is essential for a core operational component of a distributed system" - which is, I would argue, an entirely reasonable thing to want.
I quite enjoyed the rantiness on a "being entertained" basis but it did rather work against effectively making the core point.

I've seen the trend toward complexity in other projects too, and it harms not just ease of debugging, but ease of hacking.
Take, for example, Swagger UI[0]
v2 was so simple. It was vanilla JS using jQuery. I, as an embedded systems developer, was able to easily hack it so it could read in the OpenAPI JSON from a database and I even added a little search box so you could filter down the APIs you wanted to see. Super fast and easy and worked just the way I wanted it to!
Starting with Swagger UI v3, it became... extremely labyrinthine by comparison. It was completely re-written in React JS and now I need a bunch of new tooling to make changes and everything was broken out into dozens of different modular files so I couldn't find where I needed to make a given change, also not to mention I've never used React so it felt like the barrier to hackability was dramatically increased.
I'm sure full time React folks love the new architecture because it's so much <cleaner/safer/scalable/etc>, but for me the change was extremely confusing and made the tool unhackable (I tried for a few hours to get it to do what I wanted, but it started looking like I was just going to have to learn all of React and I threw in the towel), and so I'm permanently stuck on v2 for now.
> Complaining about an open source project changing technologies because you can't be bothered to learn them is a bit rich
Web technology is its own beast. I invested a long time learning and mastering AngularJS only for all that work and knowledge to be flushed down the toilet over the next few years. Web tech has terrible ROI so that's why I "can't be bothered" to learn the latest one. I'm salty specifically about Swagger jumping on <insert latest framework> instead of sticking with simple vanilla JS that everyone understands.
