In the context of VPNs for example. Some VPNs store and provide information about what sites you go to third parties. Third parties analyze it and figure out what adds to show you. Hmm… then let them show me those adds they want to show me. I do hate adds as a whole and use an add blocker, thus. But I couldn’t care less what particular type of adds they show me, they are still adds.
Someone knows what sites I go, what then. If someone curiously inquired me on this type of information I’d tell them without giving a second thought. Incomparably larger amount of data I put out just by making comments and posts.
Coworker of mine recently told me that his family’s been getting harassed for hush money by some fucker who got his son’s personal information after he visited a compromised website.
That’s why.
If all you’re thinking about are advertisers, as if they’re the only ones who can hop on board the online monitoring train, you are missing a huuuuuuge cybersecurity threat.
ETA for anyone who’s curious: yes he went to the FBI, don’t know if anything’s come of it yet
