Our gerontocracy is unprepared to deal with issues related to technology and privacy. I don't think these data brokers need to hide at all. We already see how legislators (failed to) comprehend issues related to technology in the many of unproductive congressional hearings over the past few years (Google, Tiktok, Twitter, Facebook... all brought before congress with nothing to show for it now). I think issues of technology and privacy are moving too fast for our gerontocracy to possibly keep up.
And I think our legislators show their ass in the case of the Tiktok hearing; effectively stating oh it's fine if the data is being bought and sold by a US company (Oracle).
