Now you can come claiming well that's bullshit. But that can again be said for most of the companies.
One of the things that drove me nuts about the Qanon family of conspiracy theories, despite them being insane, was the rhetoric their followers used, calling the US government "the good guys". First of all, what conspiracy theory actually suggests that the government is on their side and not out to get them, and second, do Q followers think we're in a superhero movie with good guys and bad guys?
Very rarely it backfires & we get things like this.
Overwhelmingly, most people think this is fine.
I hate it here.
I'd expect most Facebook employees working on the main project feel like they are doing good in the world helping people connect with their friends and families, organizing events, etc...
For Google I'd expect most employees feel like their products (search, android, chrome, chrome os, maps, gmail, etc...) help billions of people in positive ways.
