I believe you need to separate two things:

- The author enjoyed writing quality open source code

- The author needs to make strategic decisions for his own career and livelihood and he doesn't have enough bandwidth for both

I don't feel he is happy about the decision he needs to make and he is pointing to something dark happening to software development and open source.

Now this is not new, and didn't start with LLM. I am sure if we ask the OpenBSD devs what they think about the modern mainstream open source ecosystem, docker, full stack development, etc. they see it like we might look at LLM generated code. This is just a question how much of a purist you are.
