this is not new
even before the 'internt bubble' companies were sharing information
did you know your employer shares your information with other companies. such has how many repremands/promotions/payrises you had in work,whether you file grievances with other staff/management. your salary and your education/skills
(if a company has a professional HR department. expect your employment info to be shared)
this is because for a company to check someones cv/resume is accurate involves paying a college/university examination group an admin fee to verify you did actually get the results. this ends up with costing a company multiple fee's for multiple qualifications a potential employment interviewee may have. companies started to centralise that information and charge a lesser fee and made it faster and cheaper for other companies to find out if your information is accurate
(new employer asks old employer how accurate/truthful skills listed are, evolves into a business of its own buying and selling that info)
people thought pre millenium that only 'credit scores' contained details of their creditcard or mortgage details.. but now they find out phone companies, and contracted subscription services sell their information to credit report companies about if someone makes their regular payments, which affects your credit score too.
these days even landlords share info about their tennants
again even before the millenium retail stores and grocery stores that do 'loyalty schemes' would use and sell that info
so all this stuff aint new.. its been going on for the entire 'retail/goods and services' era of like the 1990's onwards
thanks to the internet making it easier to share info, rather than needing paper records and phone calls for references/checks
and so as the article says. even apple/google/facebook sells info about what apps people download and use and how often. we kinda accepted and knew that one as they didnt really hide it
.. s we should all just accept if you do anything online expect it to be passed around
and yes its not just 'metadata' like a score. they actually keep the detailed stuff that the assumed score is based on
one last thing.
in the UK even the government share info. i know this because when moving to a new location and not even building up much of a 'consumer map' of what i do from my new location. i start getting junk mail directly linked to stuff that was information i could only assume was from the government. simply because on a certain form i mis-spelled my name. and suddenly junk mail was appearing addressed to the mis-spelled name
