Agreed - they reason they "jumped-ship" was not to address the root issues. It was to address to hit on their vanity for working for a company that is currently in a bad light.

It says more about the individuals than it does about the company.

From what I've heard, they're fairly independent of the mothership and have their own distinct identities, similar to how people at YouTube don't consider themselves to be Googlers as much as YouTubers.

I hear that but I don't believe it for a second. In fact I noticed something really interesting...

Install Facebook and Instagram on iOS. Launch FB and note how long it takes to start, now launch Instagram and do the same. Instagram starts up nearly instantly.

Now, force quit both apps and remove Facebook. Start Instagram and all of the sudden it takes much longer to start. I don't know why this is but it certainly shows a deep connection between the apps in a way that users are probably not expecting.

Sure, but corporate culture generally always seeps into projects like these. Especially when looking for ways to monetize, since those decisions generally come from upper management at the "parent" company.
