"That same model" refers to feature teams where product managers are given predetermined roadmaps rather than discovering customer problems and solutions.
What's so frustrating here is you have all these people that realize things aren't good yet most places they turn are just propagating that same model. So these certifications, which in my opinion are bogus, but most people don't know. And just imagine you're a brand new product manager. You look online probably what, 90% of the content out there is from the feature team world or worst.
