There's a lot wrong with this post, especially the first few paragraphs. That part mostly just repeats a lot of tired myths and straw-man arguments w/r/t Scrum. There's nothing new or interesting there.

For an example of what I mean, consider this:

After the manifesto appeared, Scrum quickly declared itself to be “agile” in spite of its ...

But Scrum existed before the Agile Manifesto was created, and the creators of Scrum - Ken Schwaber and Jeff Sutherland - are signatories of the Agile Manifesto. So no, Scrum didn't just "declare itself Agile"... Scrum was part of the Agile movement from day 0.

But towards the end the post does get to an interesting point, which the author summarizes as:

If developers want the freedom to write software in sensible ways, they need to enter the market directly as either founders of companies or freelancers instead of through the comfort and convenience of existing companies.

There's something to be said for that. I've always said that a lot of the core issue here is exactly the "impedance mismatch" between the way engineers see things, and the way "the business" sees things. One way to resolve that - albeit perhaps not the only way - is what the author proposes above.
