> Let's go there: this is what the Unabomber was on about, and there has long been an effort to stop people noticing this.

There has not been "an effort to stop people noticing this". The Unabomber Manifesto has been available everywhere and published across mediums from the start. The topic beat to death by everyone from anarchists to eco-fascists to internet edgelords since it was released. It has also occupied a place of debate in academia, being studied and criticized in a lot of courses.

The Unabomber Manifesto wasn't even a particularly good critique in this topic. It just happened to become a popular one because he was a terrible person who murdered a lot of people and wanted to murder a lot more. The common criticism of the manifesto is that it was a bunch of cliches tied together with some writing that appeared eloquent, and then he forced it into notoriety by being a literal terrorist.

It doesn't stop comments like this from implying that he was on to something or the next step of implying that there's some broader conspiracy to stop us all from noticing that he had a point. The latter conspiracy breaks down when you look at how much everyone knows about the manifesto and how it has been reprinted and discussed to death for years. He even wrote and published entire freaking books from prison.
