And you are right.

Yes

It is misoginy, and misoginy is always is mis-everyone - but a tiny elite who benefits from it.
Advertisers for example.
TODO: Add "why-not-both?" meme here.
The word you might want here is misanthropy "a dislike of humankind".
It's like "all lives matter". Nobody but psychopaths disagree so why do people bring it up? What's the point?
Mostly to defend the status quo where some lives matter less than others.
I only have anecdata to go on, but in literally every case I've seen, the reason has been "because of (and in response to) someone else implying otherwise".
Because if the motivation is to save lies, why would you keep that information secret?
Maybe you can ask your friends if they have something more precise and more useful that their ego being hurt?
That could be for example "people who have a tendency to do depression are at a higher risk of suicide because Facebook has been optimizing user engagement like a psychopath".
Now yes I would be interested because that looks like an area where you can have a meaningful positive effect in the real world.
