Happened to me yesterday, I was baffled but then I found that you can request the one time password just using the email associated with the LinkedIn account, so the password wasn't compromised
I have changed the password, main mail and in the privacy settings of LinkedIn removed the visibility of the email
Indeed, you can use that for a plethora of things besides the advertising.
Also many websites are using Google Analytics as base tool for reporting and monitoring activities
Quite a big theme tbh
I'm not smart enough to make a comprehensive reply to your question that encompasses all the socialogical, economical and so on thing.
But my 2 cent on this topic as common dude is that nowadays it pretty useless to vote since both parties have scandals or some grade of corruption.
On the other hand if you don't vote you are just idle and you can't complain if things don't change if you don't act
I'm talking about almost every first world country rn not just the US
