Reading your link, it appears that the author just flatly assumes that space is not expanding, and everything else stems from that assumption.

The author provides another article to attempt to support that assumption, but their argument for that is incomplete, and while their alternative appears to offer explanations for some observations, it ignores other things (like cosmological redshift). Add in the fact that that the article appears targeted towards laypeople and there's no scientific paper to be found suggests that it's more psuedoscience and thought experiments than actual scientific investigation.

It seems unreasonable to claim that academia would reject the idea out of hand when no-one's even written a paper to attempt to submit to a peer-reviewed journal. I suspect the reason academia ignores the supposition is not commercial interest like you claim.

I've been a student of that blog. It doesn't ignore cosmological redshift. Rather, the dark energy solution notes that space measurably expands, but in a relative (it depends on the observer) way as opposed to the absolute (observed by all observers) way that is generally accepted today. When space measurably expands (whether relative or absolute) you have cosmological redshift.

Space itself not expanding is the absence of an assumption. Today it's generally accepted that space itself expands, an assumption.

Thought experiments are scientific investigation. Nothing in the rest of your point actually suggests pseudoscience.

If you showed me scientific papers that had been rejected by peer reviewers, then you might have a point. But if it's entirely articles targeted at laypeople and no scientific papers, it's pseudoscience.
