The situation is interesting, and self-hosting is indeed a very nice solution often. However, I wanted to comment on the article itself - it seems to be very heavily AI-edited. Anyone who has spent time with LLMs will easily see it. But even that's not the issue; the main issue is that the article is basically a marketing piece.
For example, the "Bridging the Gap: Why Not Just Docker Compose?" section is a 1:1 copy of the points in the "Powerful simplicity" on the landing page - https://disco.cloud/
And this blog post is the (only) case study that they showcase on their main page.
