The writer concludes that we should deploy and manage our PaaS. This answer is in the same vain as "just buy your own servers". The point of using AWS is that I don't need to manage or even worry about of it. I pay the premium of using EKS & ECS so that I don't personally need to manage my clusters. Going backwards isn't an answer.

I think the author is on to something.

I imagine hybrid solutions and infrastructure software like Nextcloud (but for PaaS and businesses) will be the next step.

If the business is large enough, choosing to become vendor-locked means becoming less cost effective and therefore less competitive.
