What you’re concerned about doesn’t stop at the employer.
Anyone with access to data being processed about you may have incentives that align similarly with your employer’s use case.
Advertisers, Internet service providers, phone manufacturers, social networks, tech platform providers, schools, families, spouses, nosy neighbours, nosy governments.
The scale at which you can build a summary about someone is astonishing.
How they breach policies, how they break laws, how they mishandle sensitive data, how they materially negatively impact customers.
This whole thing is now a litigation nightmare, and frankly I can’t believe Meta is doing this so publicly. They’ve created an incredibly dangerous and lucrative lever in which vexatious and otherwise incentivised individuals and organisations can subpoena and demand evidence which, provided the ample data available, will surely produce enough evidence given the expanse of their employer base. They simply need to have a thread to pull on, so a judge doesn’t deem it a fishing expedition.
Similarly, I worry for democracies with no checks or balances to prevent ruling parties from exploiting or abusing this power. For example, in India, there’s accusations of their equivalent of the NSA being used to spy on the opposition —- under the guise of “keep them honest”. https://www.idsa.in/system/files/book/book_IntellegenceRefor...
In other Western countries whenever this type of work is conducted, it’s usually at Director or Minister-level approval. There’s lawyers involved, it’s heavily documented. What happens when systems, or products, are given the implicit approval of this same function by their very nature?
We’re in weird times.
