Just kidding. It shouldn’t need to be said, but don’t actually off yourself.
On the other hand, if someone is just trying to make the most money, they may end up causing harm. There are many jobs like that - but the scale is more at bigger companies.
I don’t think it makes sense to judge someone based on the company they work for if you don’t actually know whether that individual’s actions are making the world a better place or a worse place.
If you are, let’s say the boat mechanic of someone making a business of dumping toxic chemicals in the sea, then you are clearly doing evil.
Similarly, if you are doing “harm reduction” at Facebook, you are still enabling them to exist, thereby enabling them to get away with doing more harm overall.
You tipped your hand with the 'damaging democracy' phrase, which boils down to "my political opponents are allowed to speak on the platform". In pursuit of your quest to destroy the freedom of expression for your political opponents, you severely damage your retirement (in my opinion, deservedly).
However when one the pick of the litter, there's a spectrum between getting $1M for a company responsible for polarization, breeding hate, and damaging democracy...to living well comfortably on $200k+ (or even $300k+) to at least try to do something meaningful. It's 8 hours a day of your time, you vote with how you want it to affect the world
