"just dont use LinkedIn" is such a narrow minded thing to say. How do you feasibly expect people to exist in society without interacting with any of these systems and corporations? if its not LinkedIn its Indeed or w/e else. They all collect data and most of them are pumping it into some kind of LLM or behavioral analysis algo. That is not functionally different than the argument for the Government doing it, except for that the Gov has a monopoly on violence.
This applies for pretty much everything in our daily life like banking, shopping etc... "just don't interact" is such a useless nothing-burger that side-steps the problem entirely. You can "solve" all societal problems by becoming a hermit, moving to the woods and living off the land... but that is not a functional or reasonable thing to do for 99.99% of people. Its baffling especially when the reasonable solution is simply having a bare minimum standards of protection across the board, which many countries already implement to great effect.
