Did you read an LLM summary of the article? It mentions all of those topics but none of them in the way you say.

The article describes a reverse-engineering effort in Bulgaria during Soviet times, but doesn't say anything anti-communist, just that direct commerce with the West was not possible at that time. It relates that effort to the author's motivation for working on an open-source circuit analyzer, and takes a pretty strong stance against uncritically adopting technology without any attempt at understanding how it works.
