It runs to the idea that perfection is the enemy of good, and how do you change perfection? In a growth company with massive scale, a system always has some risky red-line, and so it is better to spin up some competing efforts with different perspectives to tackle different needs in different ways. The key is to have redundancy of people over time and to create multiple thought leaders within a company; this makes it interesting. Then, at a future date, a "re-org" will happen to condense efforts and the real product is having a number of people familiar with the ideas spread across the company. This makes zero sense for start-ups, but when you are a risk taking company with massive budgets... strategies are interesting. You see this with VCs having stakes in similar investments as well, and the idea is the same... diversify over people rather than perfect minimal code.
