It opens with the example of rising construction costs. The only remotely relevant example here is Autodesk, but by the article's own admission, "the cost of these products remains relatively minor". And that's an overstatement: they are negligible. I guess Assa Abloy is another example, but really - mini-monopolist power? It's one of countless lock manufacturers. You can buy Schlage, Kwikset, ABUS...
In fact, no serious study of the construction industry pins cost increases on stuff like that. There are far more powerful factors at play. The laborers you hire want to be paid more than before (and the government is rising minimum wages). Compliance is getting costlier due to ever-evolving building codes, environmental and energy regulations, and zoning. Customer expectations are increasing (higher finish, more sqft). To the extent the materials are getting expensive, it's usually not your lumber mill being greedy.
I don't expect every opinion piece to offer irrefutable proofs, but there is really no effort to build a case for that claim at all.
Plus, I think the article falls for the classic trap of "rising prices are not inflation, it's <something else I don't like>".
