It being for sale means anyone can be doing it which might be a framing that would be more alarming to the law-and-order types.
But really you need a two prong solution:
1) restrict this from being collected and compiled in the first place, eliminate the ability to default to this tracking unless someone opts out
2) restrict the government's ability to use or acquire through non-market-based means. The claim here is that there's already restrictions on this vs directly surveiling, but I haven't seen directly which specific restrictions those are for buying off-the-shelf info and the article doesn't specify.
There are very really no companies that I trust to keep my data safe for 10, 20, 50 years. Leadership changes, ownership changes, etc. We have to cut it off at the source.
That's why information in government hands can be more dangerous than in corporate. A good example is when Nazis occupied Holland they used governmental data on religion (collected to properly allocate funds for places of worship) to track jews and send them to the camps.
So data in corporate hands is bad, but governmental data can be even worse.
But in all seriousness, you should know it is actually possible to use data towards good aims. Policy makers can use data to produce better answers to questions exploring issues like poverty, disease, crime, financial literacy, etc. Setting up a massive survey is slow and extremely expensive, and that makes it extremely hard to iterate on findings. Getting answers years quicker makes it possible for the government to develop better policies, and that's a good thing. Sure the Nazis were evil, and information enabled the Nazis to be more efficient and effective at implementing evil policies. But an un/less-informed government isn't a goal to strive for. Good government implementing good policies is a goal worth striving for, as there are some problems that can only be addressed at government scale.
