I would agree except that they have taken funding from investors (e.g. Amazon) and owe them a briefing on results and some plan for the next quarter/year. Otherwise they risk getting out of sync.

I think their funding is from Bezos, not Amazon, and yeah, they probably talk to them once in a while about what they're up to, but that's sort of different from a business plan. They didn't get any money until well after they were a going concern, either.

In general if you take money from an investor they want to know not only what you have been up to but what you hope to accomplish. They could have a different relationship with Bezos but I would doubt it given the way that he manages Amazon.
