The fourth amendment, of course, also applies to private actors when they become essentially agents of the state, by taking in a role traditionally within the purview of the state, so long as the state knows of the activity, more or less. If you would like a more accurate definition, you can search for “state actor doctrine” and you will find some cases about railroads drug testing employees and parcel carriers searching packages for contraband.

None of which applies to a company that sells this data to anyone who wants to pay for it.

A phrase that I learned to use recently is:

"In the private sector everything is allowed, except those that are explicitly prohibited. In the public sector everything is prohibited, except those that are explicitly allowed."

This is why in the EU (which is not a perfect society, but 'good enough'/'better than others' we got GDPR and EUDPR which cannot and should not be ignored.

If you allow the public sector to go rogue, then freedoms and right will be corroded and eventually taken away 'for our sake'.
