Now that you mention this I've seen this pattern happen and it repeats. Usually all we see is the end: a medium blog telling us why they left so and so company. They always give a reason that sounds like someone is still figuring out why they left their "dream job" without ever getting to the core. This happens more with big companies like "Stripe" than we like to believe. We sell ourselves in the comments section on how great "Stripe" is to work at while employees are being crushed with 60 hour weeks.

It does show in the products. Great products like "Stripe" start out wonderful but in time slowly move away from that initial greatness into products that slowly get worse and the company lives on in a shadow of what they once were.
