An employee not knowing what's happening at the company above them is a fault of the manager. There are some things that need to be kept secret, but if it's not one of those things, secrets are not a good thing.

It’s not that straight forward. It’s not the ICs job to know everything that is happening nor is it their job to make decisions based on pass through data, especially not a junior/mid career engineer.

Transparency and keeping people informed, yes. Sharing a bunch of info and letting every IC make their own strategy and prioritization decisions, no.
