It would be awfully surprising if virtually all companies had the same problems due to smart people suddenly behaving irrationally in the same way. It's much less surprising that smart people behave rationally in their own interests, but that those interests regularly fail to align with overall company interests.
And I think the pattern you describe is even mirrored on an institutional level. People are quick to mock Kodak for ignoring the rise of digital cameras, but they tend to undervalue the amount of risk that pivot would involve. If you're a world leader in product X, and that gets replaced by product Y, pivoting destroys the value of your expertise and puts you at risk. It's unpopular but perhaps sensible to settle on winding down profitably (the institutional version of a timely exit) instead of pivoting.
