There’s the product side, and there’s the technical side. I’m not sure what qualifies as “senior leadership,” but when a VP finally stepped into the org, all the ambitious product ideas were cut, and we landed on Nest as a product. Until then, I believe it was mostly courtship and sales pitches (I wasn’t in the room).
Apologies if this comes across as harsh, but Fuchsia always seemed to suffer from poor product judgment. I think it’s only healthy to acknowledge that. That said, it’s not entirely surprising—good product people don’t tend to stay very long at Google.
Yes, there was a mobile shell briefly. There was also a desktop shell. I think the narrative you’re describing could be better framed as a series of attempts and experiments to see if Fuchsia could find a use case and client. That doesn’t necessarily mean there was a concrete plan that was seriously contended or scrutinized.
Just to clarify, these are my personal opinions and observations. I don’t actually know what went on behind closed doors, but I’m not sure it’s all that useful to know either, for the reasons I mentioned above.
