Clearly not, but this is a circular argument. As companies expand in size they naturally increase both their needs and their resources.

Are you arguing that using SaaS developer tools like the ones in this journal entry consumes a greater proportion of engineers' capacity than self-hosting does, and that this cost difference becomes proportionally greater as a company grows? If you're right, perhaps some cloud-based startups and also larger businesses will be eaten up by more nimble, efficient self-hosted competitors.

The article clearly states how they scale this down to save on costs and dev time. No mystery here.
