>And how often are the "life cycles" really just the accumulation of bad short-term decisions catching up with the company?

I do think technical debt is a real problem, but to play devils advocate, the “life-cycle” is often a pivot from “innovation” to “maintenance”. Companies rightly begin to focus on the aspects of business that make them money and will often cannibalize R&D to focus on high-margin areas. That’s why “mature” companies often focus on innovation via acquisition.
