As a counterpoint to this, many businesses cannot exist without maintaining CRM database of who their customers are, what acquisition channel they came from, how they have responded to new products / promos / pricing / page designs, direct customer survey data, what payment methods they use, what help center issues they’ve had, what behavioral clickstream of events they used to navigate a product / store / web page, and how all these things vary by time, by seasonality, by gender, by age, by location, by income bracket, and more.

Even if the company has zero intention of selling that data anywhere else, it’s literally a bare minimum requirement to be able to not go bankrupt and layoff all their employees from failing to competition or failing to correctly measure and respond to intricate market signals.

I am a deeply privacy conscious person, but it does annoy me when the counter response to data brokerage or selling personal data is to go way too extreme in the other direction and vilify or try to make illegal the huge amount of data capture that is completely, non-optionally required at a basic minimum level for any modern business to have any hope of not failing.
