Almost everything based in technology spies on everyone now a days and most people are alright with it. I don’t understand why people are okay knowing this spying exists. Louis Rossman does a great job here showing us the disgusting tactics used by big corporations to gaslight people into believing them over what these companies are really nefariously up to.
If you live in the US, most likely data brokers.
Really seedy industry centered around buying and selling your personal information, compiling public records from government sites to build a profile of your location, previous addresses, jobs, biological sex, given sex, phone numbers etc, and then cross referencing that with online data from ad trackers and targeting to build a more detailed profile of who exactly you are specifically.
This stuff doesn’t even scratch the surface too.
US law enforcement has also been openly using data brokers to bypass certain privacy protections/rights granted to people who live in the US, where things like a warrant or subpoena would usually be necessary
