This will, naturally, cause hairs on necks to rise waiting to scream back "What are you talking about? Of course Agile is the problem!" But really, the problem is that any business trend/fad is inevitably doomed to become a hollow shell of what it was intended to be.
Or more pointedly: Businesses don't really want to overhaul their development process, and any new process integrated will inevitably become just an extension of whatever they were doing before. This is basically what the article's saying without directly saying it.
I mean, the very first phrase in the Agile manifesto is:
> Individuals and Interactions over processes and tools
And yet see how many anecdotes in this thread are about how the most annoying part of Agile is the rigid adherence to certain processes. If 1 week sprints are too short, change them to 4 week sprints. Figure out the cadence that makes sense for your team. That's what Agile is supposed to be about.
Regardless of whatever Large Co wants to call their development process, let's stop calling it Agile and start calling it what it really is: Waterfall with a Kanban board and shorter deadlines.
