Apple has a no-bullshit work culture (you aren't infantilized like at many other Silicon Valley companies) and the employees really do value and care about their work and its impact in the grand scheme of things.
Unfortunately, this doesn't extend to upper-management, which is why we see things like Apple 'forgetting' to implement cloud-wide E2EE at the behest of the FBI, or turning over iCloud servers to the Chinese government, creating a massive corporate-sponsored state-surveillance network.
It’s hard work but much more interesting than my previous jobs, and people _really_ believe in the values like privacy which I like.
