Engineers are pretty jaded about plans expressed by authority, especially when there are obvious pressures opposing those plans. Yearly planning doesn't matter when a reorg will change the trajectory by Q3. Sprint planning doesn't matter when you know a fire will hit before then and you won't be given enough time budget to fix it well enough for that not to happen again next sprint. Project planning doesn't matter when the whole point is masturbatory spreadsheet production before you've actually taken a dive into the hairier details and figured out what's possible and what's necessary. That barely working demo strapped on top of a non-existent backend they swore would never become production? Congratulations, you have two weeks to build the next fake demo on top of it, but the base has to actually work now.

Maybe Jared just broadcasted uncertainty and was wrong, but given his position he's not being given the normal grace you might extend to an engineer you trust.
