It's semi-reasonable. The individual parts are reasonable but putting it together to create a branded methodology™ which is "my way or the highway" was the beginning of the agile-industrial complex as we know it.

You might make the case that Kent Back has actually put together two lines of code and run a compiler (even started JUnit) and the thousands of imitators who talk just like Kent Beck haven't, but if you're going to be critical of the agile-industrial complex you have to be critical of the founder too, who created a toxic style of discourse and a piratical business model of agile consulting.

The agile-industrial complex came from Scrum and its certified trainers, and its imitators such as SaFE, not Kent Beck and XP. Kent disappeared for a while to raise goats in Oregon, then worked for Facebook and other companies (as an employee). He’s the last person you should be blaming for what Agile’s become.
